Since we have the new sit-for implementation, I have a lot of times
when Emacs just pauses in busy waiting for input. This happens
spontaneously. One situation where it happens frequently is when
reading news with gnus. If I type C-g at such a time with
debug-on-quit set to t, I just get
Debugger entered--Lisp error: (quit)
in the *Backtrace* buffer.
In contrast, when Emacs is actually waiting in a non-busy wait for
input, the backtrace is
Debugger entered--Lisp error: (quit)
signal(quit nil)
keyboard-quit()
call-interactively(keyboard-quit)
and this is what I would expect without those random lockups which
tend to last for seconds and gobble up CPU power.
This is really a nuisance. The change to sit-for is a fundamental
change to some core mechanism of Emacs, and it is currently seemingly
breaking quite a few things, apart from causing strange effects.
It does not look like the implications of this code are obvious to
anybody.
