OHM crashes when X does.

[cjb]

As noticed by jg; after ctrl+alt+delete, X returns but ohm doesn't.

OHM appears to notice that the dpy has gone away and frees it, but then attempts to reuse it later.

OHM crashes when X does because X forces all of its clients to exit when it crashes. Adding an XSetIOErrorHandler() callback doesn't help.

There is no workaround short of longjmp()ing to ensure the handler method never actually returns to Xlib (or moving the X client into a separate process from the rest of OHM). How ridiculous.

The shortest workaround is going to be to have OHM respawn via inittab in the same way that X does. I don't know how well that will work yet, though.

I think libxcb would be an elegant solution to this problem. The library itself is just 100KB, plus a bunch of ancilliary libraries of a few KBs each, one per extension.

We can conveniently install the Fedora 8 libxcb package on our F7+ system.

Temporary workaround (Bernie's idea) is to exec() /usr/sbin/ohmd in the X handler. Long-time fix is to move to Xcb sometime after Update.1.

Tested and pushed to Joyride.
