In userret to catch processes sleeping in the kernel
In syscall to catch processes running in userland. I realize this is
poor since the process could spend quite some time before going in 
the kernel. Sending it a signal is not possible because it will be 
reported to wait4(). What else can be done?

It works fine with java. I don't have the OpenOffice monster at hand.
