Hi there,
grep(1) does not seem to skip FIFOs when told to.

I think you need a patch to fix it, the bug is in ggrep, it tries to
open a FIFO before checking if it is a FIFO, then blocked.

or the patch:

The patch opens file with O_NONBLOCK, then turns off O_NONBLOCK,
and only checks if a file is a FIFO in reset() function.
