Ah... okay, [I'm prolly not gunna put this quite right, but bear with
me...] so a fifo is more like a 'standard stream' like STDIN, STDOUT,
STDERR but linked to the filesystem instead of a filename linked to a
'standard stream' ...

... and cat can't be used to 'write to the file' as it would prolly
overwrite the fifo - but can be used when redirecting
stdin/stdout/stderr only.

I _think_ I see... but correct me if I'm wrong.

[[ P.S. ISTR seeing about 1/2 decade ago, a webpage that made fun of
people who used 'cat' in extraneous to downright stupid ways - it was
called something like "stupid 'cat' tricks" or somesuch... I guess I
just earned an honorable mention on that page... ;-) ]]
