that key_cache bug, 17332

This massive fix has been pushed into 5.1.19 and so far I cannot repeat any crashes!! Well done Ingo and reviewers ! My testing continues!

partition maintenance?

It seems doing any partition maintenance in combination with some concurrent workload will fail with many different errors in 5.1. For more or less the same underlying lack of locking, I've filed a few bugs.

To cause a myisam table corruption or server crash (or innodb assert) all you need is 1 thread inserting, and 1 thread altering/optimizing partitions: Of course, the more threads the easier the problems will happen..
