Oh my eyes, my beautiful eyes.

ouch.

Offtopic: (on topic?)  I've been playing with P9P, getting libdraw to =20=

open applications applications in the same window they were started =20
it.  I've got it working except for the dreaded X11-is-single-=20
threaded race condition.  Within a single proc it's easy to wrap the =20
offending calls in a lock, but I'm looking at the case where =20
different procs need to use the same window.  It seems that all I =20
need is a nice, cheap, inter-process lock.  What's the most portable =20
answer?

I'm astounded that this works as well as it does, by the way, without =20=

taking a lock: only when a window manager likes to bombard events =20
down upon all the processes do things get hairy -  like running OS =20
X's aqua-wm that wants to redraw the window contents during a =20
resize.  Rio has no such problem, and doesn't trigger the X11 sync =20
problem as a result.  Astoundingly usable.
