threads/84778: libpthread busy loop/hang with Java when handling signals and Runtime.exec

[freebsd at spatula.net]

Another bit of information of interest: sending the process a kill -stop 
(-17) after trying to stop it with ^Z *will* cause the process to stop.

Sending it a kill -stop without hitting ^Z will also cause the process to 
stop normally.

In either case, however, resuming from the shell with fg will cause the 
same infinite-loop behaviour.  Resuming with a kill -19 will also cause 
the infinite-loop behaviour.

Sending a regular kill signal also causes the infinite-loop behaviour. 
The process has to be killed with a kill -9 in all cases once this 
behaiour starts.
