signal masks and garbage collection.

[Keean Schupke]

I have a problem with c_sigprocmask from the Posix library. This is 
supposed to set a signal mask for the process
(but it appears it actually only sets it for the thread). I need some 
way of calling sigprocmask before the garbage
collector thread is started so it inherits the same signal mask (or a 
way of setting the signal mask of the garbage collector
whilst running). Any ideas?
