The reason is that on RHEL4 we were getting this error with all the 
tests that
used the system calls code.

     java.lang.RuntimeException:
   {frysk.proc.LinuxTask@4fa960,pid=10898,tid=10898,state=runningInSyscall}
   in state "runningInSyscall" did not handle handleSignaledEvent

this is on the following kernel:
+ uname -a
Linux hs20-bc2-3.build.redhat.com 2.6.9-34.ELsmp #1 SMP Fri Feb 24 
16:56:28 EST 2006 i686 i686 i386 GNU/Linux

I have not had a chance to reseach it more. I wanted to get the patch in 
for the release. The truth is even if it is some
kind of kernel bug it is not likely to get fixed and we will have to 
handle it in the same way that the patch did :)

I'll know more soon :)
