Re: cygwin deadlocks due to broken select() when writing to pipes


Ok, well it wasn't 100% cured with the TTY flag removed but it stopped it
being a 100% daily problem to an "every other day or so" problem (depends on
the direction of the wind I think).

Why does TTY affect the behaviour of rsync and cron jobs?

Also, this may be a silly question, but why does it try to kill my cron jobs
when I log off from my user?  Shouldn't they be running no matter what user
is logged in, and regardless of whether I log in or log off?  They
definitely shouldn't be killed or need to be killed.
