On an RS/6000, zwgc dumps core on selections (upon typing SHIFT-LEFT
button in the Zephyrgram to cut text), but only sometimes. It is likely
to be some form of race condition which was present before but occurs
much more frequently on the rios, and is easier to repeat. Here is the
stack trace:

I will look at this a bit when I get a moment. A sample core dump is in
~ckclark/core.zwgc, but I can generate another one on the fly fairly
quickly.
