+My alternative idea, which seems simpler than all this tricky locking
+stuff, is to introduce a new lock file (really a flag file implemented
+using a lock), which tells the commit hook that the CGI is running, and
+makes the commit hook a NOOP.
+
+* CGI takes the wikilock
+* CGI writes changes to WC
+* CGI sets wclock to disable the commit hook
+* CGI does *not* drop the main wikilock
+* CGI commit
+* The commit hook tries to set the wclock, fails, and becomes a noop
+ (it may still need to send commit mails)
+* CGI removes wclock, thus re-enabling the commit hook
+* CGI updates the WC (since the commit hook didn't)
+* CGI renders the wiki (always. commits may have came in and not been
+ rendered)
+* CGI checks for conflicts, and if any are found does its normal dance

+
+I agree, and I think that the second case points to the hooks still being
+responsible for sending out commit mails. Everything else the CGI can do.
+
+I don't believe that the first case is actually a problem: If the RCS
+commit does not introduce a conflict then the CGI commit's changes will be
+merged into the repo cleanly. OTOH, if the RCS commit does introduces a
+conflict then the CGI commit will fail gracefully. This is exactly what
+happens now if RCS commit happens while a CGI commit is in progress! Ie:
+
+* cgi takes the wikilock
+* cgi writes change to wc
+* svn commit -m "conflict" (this makes a change to repo immediately, then
+ runs the post-commit hook, which waits on the wikilock)
+* cgi drops wikilock
+* the post-commit hook from the above manual commit can now run.
+* cgi calls rcs_commit, which fails due to the conflict just introduced
+
+The only difference to this scenario will be that the CGI will not drop the
+wiki lock before its commit, and that the post-commit hook will turn into a
+NOOP:
+
+* cgi takes the wikilock
+* cgi writes change to wc
+* cgi takes the wclock
+* svn commit -m "conflict" (this makes a change to repo immediately, then
+ runs the post-commit hook, which becomes a NOOP)
+* cgi calls rcs_commit, which fails due to the conflict just introduced
+* cgi renders the wiki
+
+Actually, the only thing that scares me about this apprach a little is that
+we have two locks. The CGI takes them in the order (wikilock, wclock).
+The commit hook takes them in the order (wclock, wikilock). This is a
+classic potential deadlock scenario. _However_, the commit hook should
+close the wclock as soon as it successfully opens it, before taking the
+wikilock, so I think that's ok.
