Crash when creating new subprocess

[artemm-bochkarev]

Describe the bug
When a java-application with embedded jcef tries to create a subprocess then it sometimes crashes (with SIGABRT).
This crash is observed only in OSX Sonoma with x64 architecture.

To Reproduce
Steps to reproduce the behavior:

1. Checkout latest jcef master. Open tests.simple.MainFrame.java and replace method main with next code:

public static void main(String[] args) {
        if (!CefApp.startup(args)) 
            return;

        new MainFrame("http://www.google.com", true, false);

        Thread.sleep(5000);

        Runnable testFork = () -> {
            int count = 10000;
            for (int c = 0; c < count; c++) {
                ProcessBuilder pb = new ProcessBuilder("echo");
                pb.command().add(String.format("Hello %d", c));
                pb.redirectOutput(ProcessBuilder.Redirect.INHERIT);
                pb.redirectError(ProcessBuilder.Redirect.INHERIT);
                try {
                    Process p = pb.start();
                    int res = p.waitFor();
                    if (res != 0)
                        System.err.printf("test subprocess returns %d\n", res);
                } catch (IOException e) {
                    e.printStackTrace();
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
        };
        Thread t1 = new Thread(testFork);
        Thread t2 = new Thread(testFork);
        t1.start();
        t2.start();
    }

3. Compile and run java on OSX Sonoma x64 with next arguments:
   java -Djdk.lang.Process.launchMechanism=fork -classpath COMPILED_PATH tests.simple.MainFrame
4. See crash.

NOTE: if some 'modular' problems observed then next VM-options will be usefull:
--add-exports java.desktop/sun.awt=ALL-UNNAMED,jcef --add-exports java.desktop/java.awt.peer=ALL-UNNAMED,jcef --add-exports java.desktop/sun.lwawt.macosx=ALL-UNNAMED,jcef --add-exports java.desktop/sun.lwawt=ALL-UNNAMED,jcef

Expected behavior
Expected: test will not fail.
Observed: crash (at some iteration).

Versions (please complete the following information):

• OS: MacOS 14.4, x64
• CEF Version: 122.1.9

For me this happens after having my computer up for about 1-2 weeks. (It has been annoyingly happening for several YEARS, across 3 different computers and different versions of MacOS X.. from 10.11, 10.15, 11, and 12).

When the crashes start I also see the following other oddities on my computer.

1. file open/save dialogs in ANY application take ~ 30 seconds to open
2. any chrome-based or webkit-based browser fails to start (no safari, no google chrome, nor any app using CEF, slack, jetbrains IDEs, nothing that kicks in and uses the CEF)
3. no camera access works (or takes ~ 30second to a minute to work)
4. sharing screen within firefox is slow as well (takes ~ 15-20 seconds to start streaming in a google meeting).

the ONLY fix I have had it so completely shutdown and restart my computer.
