Yes, got that. There are quite a few timers in `timer-list' and
`timer-idle-list'.
,----[ C-h v timer-idle-list RET ]
| timer-idle-list is a variable defined in `C source code'.
| Its value is shown below.

`----
Is it documented somewhere what the individual entries of these vectors
mean? The fifth entry seems to be the SECS or REPEAT argument given to
`run-with-{,idle-}timer', the sixth entry is the function to run, and
the seventh is the function's args, but what are the other entries?
But anyway, I think even when there's some timer that takes too long,
the cursor should never disappear completely. So maybe a redisplay
should be forced whenever the cursor is set to visible again and there
has been a redisplay when the cursor has been invisible. That would
ensure that if blinking stops due to a timer or processing of input, at
least it stops in the visible state at the cost of at most one redisplay
which hadn't happened otherwise.
Bye,
Tassilo
