Subject: [PATCH] Note that Emacs pauses when handling sentinel errors

Noting this behavior and variable here makes it easier to understand
the behavior of Emacs when a sentinel has an error.

* doc/lispref/processes.texi (Filter Functions): Note that Emacs
pauses when handling sentinel errors.
(Sentinels): Note that Emacs pauses when handling sentinel errors.

   While a sentinel is running, the process sentinel is temporarily
 set to @code{nil} so that the sentinel won't run recursively.
