[After running the same RMAIL for several days, deletions slow; but
not immediately. Using the `emacs/src/emacs' executable of 2005 Mar
30.]
I think you said it was spending most of the time in regexp matching.
Is that right? If so, can you determine what regexp it spends most of
its time matching? ...
Here are three instances. Each instance involved deleting 50 messages
each and suspending in the middle of the action for GDB.
In instances 1 and 3, `xbacktrace' showed "rmail-reformat-message".
Instance 2 did not.
In instance 1, `backtrace' (not `xbacktrace') showed
"adjust_markers_for_delete"; the other two instances showed
"re_match_2_internal".
