There is something seriously wrong with C-g.
It is very dangerous.

Emacs often crashes for me after trying to break blocking operation
using C-g twice.
It just prints a list of threads and crashes.
This has been happening for a long time;
I guess since introduction of threads.
It probably has something to do with disruption of blocking
network operations or garbage collection.

Two weeks ago, it even truncated ~/.emacs to 0 size.  This happened once
so far.

All with emacs -nw.
