Quiting always worked by setting a flag, tested by the QUIT macro.
However, as I implemented it, some constructs used to specify to quit
immediately straight from the signal handler.
I see that this feature has been deleted. That is going to cause a
bad results. There are quite a few places in the C code of Emacs
where execution can get stuck; that's why I added immediate quitting.
The problems I fixed that way have all come back.
What was the reason for this change?
I think we need to revert it, and fix whatever problem
in another way.
