My turn to disagree, see my reply to you in another thread:
http://lists.digium.com/pipermail/asterisk-users/2005-April/101447.html

To be more specific, a while ago I was doing this:

exten => h,1,MYSQL(...connect...)
exten => h,2,MYSQL(...write a record...)
exten => h,3,MYSQL(...disconnect...)
exten => h,4,Hangup

because I had got into the habit of calling Hangup inside h. I found that
i was getting TWO records written to the MYSQL database, because my Hangup
was causing it to call the h extension again.

It didn't continue to go round and round, so there is some check in there,
but that check was not soon enough.

Removing the unnecessary h,4,Hangup cured the problem.

This was several months ago; I haven't tried reproducing it in more recent
versions.

Cheers
Tony
