Description:

After many calls of Runtime.getRuntime().exec(), which starts an external
process, Java hangs reproducably in a STOP state and cannot be killed. (Not even
with kill -9)

How-To-Repeat:

Run any Java application, which makes extensive use of
Runtime.getRuntime().exec(). With my application, I can reproduce the problem within an hour or so - on two
different machines.

Fix:

Apply David Xu's patch to kern_thread.c as described in

http://lists.freebsd.org/pipermail/freebsd-current/2004-November/042407.html

That change is also commited to 5.3-stable.

Why is this a PR? It's fixed in both -stable and -current.
