str.find return -1 when the substring is not found, -1 evaluate
to True and is a valid index, which can lead to bugs.
Using alternatives when possible makes the code clearer and less
prone to bugs. (and __contains__ is faster in microbenchmarks)
old style: symlink to pid
new style: symlink to hostname:pid
if lock code finds new-style lock, it breaks lock if locking pid is on
same machine and pid is not alive.
otherwise, lock is left alone. this makes locking code safe with
old-style locks and with locks on other machines.
new code makes server part of mercurial more robust in case machine
crashes, power fails, or crazy user does kill -9.
- change the wait keyword from lock.lock to timeout,
a negative timeout of means "wait forever"
- refactor the two lock functions from localrepo.py
- make them use the timeout (default 1024, can be changed
with ui.timeout in the config file
- update the doc

Make makelock and readlock work on filesystems without symlink support.
This way you can have a repository on a fat partiton, e.g. a USB stick.

Fix troubles with clone and exception handling
Clone deletes its directory on failure
This was deleting the lockfile out from under the lock object before
it got destroyed
This patch shuts lock up and makes the cleanup code for clone a little
cleaner.

[PATCH] Enables lock work under the other 'OS'
From: K Thananchayan <thananck@yahoo.com>
os.symlink is not supported under Windows. This patch
introduces util.mklockf, util.getlowner that use
regular files under Winodws but symlink under unix.
tweaked by mpm:
- changed function names
- fixed to work on UNIX
