I do need auto-release semantics - after X time the lock should be released automatically. I don't think I'll write an SQL implementation, the implementation in GigaSpaces was rather easy and good enough for us - most of the time was spent on writing the tests anyway.

FYI, MySQL has support for application locks in the form of RELEASE_LOCK() and GET_LOCK(). Those are just named mutexes you can create, without meddling with tables. More info here: <a href="http://dev.mysql.com/doc/refman/5.1/en/miscellaneous-functions.html" rel="nofollow">http://dev.mysql.com/doc/refman/5.1/en/miscellaneous-functions.html</a>. Those functions are pretty neat and sometimes very convenient, but I don't know if they are any good for you.
