"ping" not reconnecting in Python MySQLdb client interface

I have some long-running Python programs that can be idle
for hours, and, of course, the MySQL connection times out.
So I call
at the beginning of a new request cycle. This should
reestablish the connection, but it doesn't:
Traceback (most recent call last):
File "rateapiv1.fcgi", line 60, in QuickSitetruthQuery
db.ping() # reattach connection if necessary
OperationalError: (2006, 'MySQL server has gone away')
The MySQL server is up, and new connection attempts succeed.
This problem was reported two years ago relative to TurboGears:
I suspect that MySQL has auto-reconnect turned off, but doesn't document this.
(MySQL 5 on Fedora Core)
