[Message part 1 (text/plain, inline)]

timer-idle-list

working emacs:
([nil 0 0 500000 t jit-lock-context-fontify nil idle 0])

broken emacs:
([nil 0 0 500000 t jit-lock-context-fontify nil idle 0] [nil 0 0 500000 0.5
blink-cursor-start nil idle 0])

Although calling cancel-timer on the timers does not fix the problem,

I have also noticed that, with toggle-debug-on-quit on, just typing C-g
while in the normal writing buffer will always send me to the debugger on
only one line:

Debugger entered--Lisp error: (quit)
  internal-timer-start-idle()

This happens in the broken emacs only, and C-g here does nothing in the
working emacs. Likewise, in the broken emacs, while I am highlighting text
with C-space, C-g will 50% of the time cancel the highlight and 50% of the
time open the above debugger on the timer start function. In the working
emacs, of course, it cancels the highlight 100% of the time.
