Personally, I find the behavior of myisasmchk to be a bit "beta" when it
comes live tables. It would be real easy for myisasmchk to refuse to run
when mysqld is running. That should be a built-in precaution. I can
understand possible objections to myisasmchk globally locking tables out of
the blue (it might disrupt what some clients are doing), but if myisamchk
cannot run on a live table, it should not run on a live table. As simple as
that.
