Summary:                    [patch] Race condition in ast_db_get()
Description: 
ast_db_get() may retrieve a wrong value because the data are copied
to the variable value after dblock is unlocked.
The copy should be done before unlock.

This can be reproduced on our cutomer's environment which is based on
Asterisk 1.2.18. I don't test it on the 1.4.x yet, but I believe that
this can be reproduced also on Asterisk 1.4 or later.

Attached patch will fix the problem.

Okay, looks like I was a bit too hasty.  I will have this committed
shortly.
