Should _XIOError really exit() ?

[Jeremy Huddleston]

Should _XIOError in libX11 really exit() even if the developer provides their own io error handler?  That seems extreme and prevents recovery.  It took me quite a while to actually discover that I was exiting at this point:

(gdb) bt
#0  0x00007fff8673d3e3 in exit ()
#1  0x000000010040c006 in _XIOError ()
#2  0x0000000100412a62 in process_responses ()
#3  0x0000000100412eb1 in _XEventsQueued ()
#4  0x00000001003fee79 in XPending ()
#5  0x00000001000305df in xpbproxy_process_xevents () at x-input.m:94
