Subject: why does message-generate-headers take so long?

Hi all,

Sending a message from CVS Emacs + CVS Gnus on Red Hat Enterprise
Linux Workstation 4 (x86_64) takes quite a bit of time, so I profiled
all message-* functions to see where the time hog was.  I'm inserting
just the top 9 results:

Clearly, the most time is being spent in message-generate-headers, and
the other long times are accumulated with it.  There are a lot of
(while (re-search-forward)) loops, but this message was just a few
lines long!

Can anyone think of a reason why that routine would take so long?  Why
is it being called twice?  Is there any way to speed it up?

Ted
