I don't see this in Emacs 20 and it seems to be very hard to reproduce
in Emacs 21.  

We had similar symptoms when we changed the buffer in a timer function
and the true cause was probably a bug in Emacs' C code. 

I'm not sure whether this has something to do with timer functions.
Usually we don't run code in timer functions, but it can happen if a
process filter aborts prematurely due to an error.  The timer is then
started to process remaining requests later.  Maybe you can see some
error message in the *Messages* buffer.

Anyway, I can't reproduce the bug so it's hard to say what should be
fixed.
