myqsldb warning problem

Thanks for the tip. I tried it and it worked for the smaller update
strings but when I tried with the larger ones I get the following
error:

Error:2006: Mysql server has gone away

I seemed to have resolved that error by updating 1000 records at a
time.

I am quite sure there are no errors in the data because updating one
record at a time gives no warnings or errors but using the same data,
as soon as I start updating the records in groups, warnings start to
show up. (I tried updating 10 records at a time and it still gives
warnings occassionally. ) When I put a huge string (one was over 5 MB)
in cursor.execute(mystring), I get the above message. The 1000 record
update has around 200KB string and it does not give the error (so far)

I suspect either MySQLdb or mysql itself has a problem with block
updates.
