            Bug ID: 111587
           Summary: Running a native process may introduce up to 1 second
                    additional delay
           Product: classpath
           Version: 0.99
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: classpath
          Assignee: unassigned at gcc dot gnu.org
          Reporter: guillerodriguez.dev at gmail dot com
  Target Milestone: ---

Running a native process and waiting for it to terminate may take up to 1
second longer than necessary.

Test code:

    long t0 = System.currentTimeMillis();
    Process process = Runtime.getRuntime().exec(args);
    int res = process.waitFor();
    long t1 = System.currentTimeMillis();
    System.out.println("Result: " + res + ", " + ((t1 - t0) / 1000f) + " s");

Sample output:

    $ jamvm Run sleep 0.1
    Result: 0, 1.002 s
    $ jamvm Run sleep 0.9
    Result: 0, 1.002 s
    $ jamvm Run sleep 1.1
    Result: 0, 2.002 s
    $ jamvm Run sleep 1.9
    Result: 0, 2.002 s
    $ jamvm Run sleep 2.1
    Result: 0, 3.002 s
