that man page merits close reading. it only speaks about 'Xlib', the "client
library", not (the underlying) X (server). another pertinent man page, re the
event/interrupt issues snipped from below, is 'XIfEvent(3)'. my understanding
(from somewhat dim, 20+ years old memory) is that whenever the window "object"
is accessed, you'll need some kind of mutex/XLockDisplay guard arrangement,
still.
another "rant" re "nice, verbose error message". a few days ago, in an email,
needed to ask what the person (also an Ubuntu user, as it happens) got in reply
when executing "$ which badname", since "badname" did not seem to work. answer:
"nothing (an empty line)". the default behaviour for 'which' is to print (to
stderr) a message like "which: no badname in ($PATH)". what I do not understand
is why the Ubuntu maintainers expend "man-hours"/time + effort on making s/ware
_less_ informative, and therefore less valuable, to the user. (it sort of
boggles the mind, and that's before the "conspiracy" paranoia kicks in! :-))

a "hacked" Tclsh?! ;-) like the idea though, to be able to interactively build
up scenes would be way cool.
