The bug does not seem to happen if the error occurs before terminal
initialization or if I comment out all xfree()s in delete_frame.
Update: yes it does, although it is much rarer. Or maybe it's
another bug.
Update: Some of these errors may have been caused by having more

file handles than FD_SETSIZE.
