Re: Mersenne: Front-end design

[Pierre Abbat]

I suggest a couple of named pipes for control (the front end writes to one and
reads from the other, and mprime vice versa). Since writing to a pipe whose
reader is stuck can get you blocked when the pipe is full, and writing to a
pipe with nothing at the other end results in a SIGPIPE, mprime should not
output anything to the pipe unless told to do so, and should trap SIGPIPE and
turn off output.
