+The problem with --post-commit is that if you delete some pages in $SRC, ikiwiki --setup setupfile --post-commit will not delete them in $DEST.
+
+I add the following to .hg/hgrc:(I use changegroup since I don't think we need refresh per changeset, please point out if I am wrong.)
+
+ [hooks]
+ changegroup = hg update >&2 && ikiwiki --setup path.to.setup.file --refresh
+ post-commit = ikiwiki --setup path.to.setup.file --refresh
+
+I tried the follwing commands in $SRC:
+
+ touch deadlocktest.mdwn
+ hg add
+ hg ci
+
+No deadlock happens. (Also I push to the $SRC from another machine, again, no deadlock. If there is conflicts between $SRC and my own repo, hg pull will abort. You have to pull, merge and push again.)
+
+
+
+Of course these tests are too simple. The problem is I have no idea when the deadlock will happen. If someone is kind enough to point out, I will run more test.
