Stevens' APUE (if you do any Unix programming and you don't have this 
book, run don't walk and get it ;-) ) says: "POSIX.1 does not specify 
the order in which signals are delivered to a process. The Rationale for 
POSIX.1 does suggest, however, that signals related to the current state 
of the process, such as SIGSEGV, be delivered before other signals."

AFAIK we are not using any of the signals he is referring to in the 
second sentence, so FIFO should be fine.
