 Yeah, pretty sure they're harmless though. Something along the way
(wmii? rc?) is setting up a signal handler for SIGPIPE, which is of
course inherited across forks. Combined with the fact that "ixpc read"
doesn't check the return value of its write to stdout and you've got a
process that won't die (at least, until you close wmii - it does check
the return on the reading side).
 At a guess, I'd say this is p9p related - part of turning signals
into notes? But I'm not familiar with the details there, and never
tracked down the cause.
