This could be the same problem reported under MacOS X as PR#4666 in
the bug tracker. Apparently, MacOS X doesn't allow a process having
multiple threads to perform an exec*() system call. Maybe FreeBSD has
the same limitation.

The "release 3.11" branch of the CVS contains a tentative fix for
PR#4666. It isn't yet propagated to the CVS trunk. You can get this
branch using "cvs co -r release311".
Hope this helps,
