It appears that MySql is doing funny things to SIGALRM.

No, it doesn't. It's the first bullet. The alarm signal is received. C calls are not interruptible, so calling the handler is delayed until the C code returns. alarm is working as expected.

1) Is this problem fixable?

You can interrupt C code by using unsafe signals, but it can leave the process in a weird state.

2) The whole purpose of this exercise is to find a way to get out of the MySql operation if it takes longer than 5 sec. to do MySql.

Perhaps you should start a thread with that question.
