getSignalMask ghc6.0.1

I'm trying to understand the ghc signal implementation. 

I can't do much with the provided examples, because getSignalMask exits 
the program with:

Fail: invalid argument
Action: getSignalMask
Reason: Invalid argument

I'm using FreeBSD 5.0 with ghc6.0.1. 

Is there any tutorials or explanations about posix signals/threads in 
ghc out there?
