Indeed. The old version returned false on Fedora 7, the new version
returns true. Meaning in particular that several tests in
TestTaskObserver and TestTaskObserver now run while they didn't before
this patch. But this doesn't seem to be the root cause for the execvp
issues.

The thing that worked around it for me for now seems to be to disable
the frysk.rt.TestStepping.testASMSingleStep() test that seems to fail
with ERROR java.lang.ArrayIndexOutOfBoundsException: 0
Apparently this failure causes no more file descriptors to be available.
Reported as http://sourceware.org/bugzilla/show_bug.cgi?id=4751
And adjusted the TestStepping accordingly.

  * TestStepping.java (testASMSingleStep): Add unresolved for bug #4751.

Cheers,
