[fpc-pascal] Forcibly terminating a thread

[Mark Morgan Lloyd]

I've got a program here which, under some conditions of testing, ends up 
with a thread stuck inside a system call (detail: a mainframe emulator, 
which is still trying to read a damaged punched card when the operator 
hits the power-off button).

Is there a way of sending an unambiguous system-level kill signal to a 
thread? KillThread(ThreadID) doesn't appear to be brutal enough, and I'm 
unsure of the correct way to access pthread_kill().
