for project clisp on SF.net,
"Concurrent Versions System (CVS) 1.11.17 (client/server)"
via SSH on cygwin and linux.
During CVS commit, I often get this messages:
Message: [22:06:14] waiting for sds's lock in
[note, "sds" is myself]
then, after a few minutes, commit succeeds.
the CVS experts looked at syncmail code and suggested
"syncmail uses CVS commands to generate a diff to
include in the mail -- if it tries to do that before
finishes, it will block waiting for your commit's lock.
I would suggest changing syncmail to use "cvs -n" for
which will ignore the lock."
