Summary: uninit mem read w/signals

Initial Comment:
if the signal()/sigaction() fails,
uninitialized memory is returned.

the attached patch fixes the problem
(didn't test signal() path, only the sigaction() path)

Assigned to Barry.  Neal's surely correct that we shouldn't 
be ignoring errors, but returning NULL isn't right either.  
Should we force return of SIG_ERR then?  That's the only 
*natural* "error return" value, and there's a backward 
compatibility problem here since we don't document anything 
about error returns for the {get,set}sig functions, nor do 
any of the places we call these check for an error return.
