Details:
When grep encounter a FIFO it open it without the O_NONBLOCK parameters that
made it block indefinitely.
I know this can be resolved by using -D skip options, but don't know if it's
the normal behaviour of grep. I report this, as I thought in that case most
user wouldn't understood why grep block.
exemples:
mkfifo toto
grep -R tata *
(grep block waiting for open to return)
