Mercurial HG on Tortoise stuck - waiting for lock on working directory...

[Catarina Runa]

Over night, my Tortoise stopped being able to push to my work repo, even though both my locks show free.

I get waiting for lock on working directory of \\uGames/MyGameRepo held by process '24012' on host MyHost.

After a long time of trying to push, I get abort: working directory of \\uGames/MyGameRepo: timed out waiting for lock held by MyHost:24012.

There is a good post on StackOverflow, but none of the solutions there has resolved my problem.

I cannot push anything... How can I fix this?
