X i/o errors

[Mike Oliphant <oliphant ling ed ac uk>]

I'm having trouble with some users of one of my gtk apps getin X i/o
errors. The problem occurs when I fork()/exec() another process from
within the gtk program. I've seen other people mention this kind of thing,
and I've tried the workarounds mentioned -- doing
close(ConnectionNumber(gdk_get_display())) doesn't seem to help.

Here is a backtrace of the error. Any help would be most appreciated.
