[CDash] reducing cdash database size

as a data point, I've also had problems with this, in fact I got a 
notice from the hosting company that MySQL would be disabled for my site 
unless I reduced the size of the database. it may have been my fault 
initially as I had not set CDASH_AUTOREMOVE_BUILDS='1'; in the local php 

Unfortunately there is some problem with the CDash autoRemoveBuilds.php 
scripts, it seems that they take too long to run(ERROR 2013 (HY000): 
Lost connection to MySQL server during query/ERROR 2006 (HY000): MySQL 
server has gone away), but in any case the auto remove scripts left the 
database in a corrupt state (specifically the test table) and now 
nothing works. I'm planning at some point to nuke the whole thing and 
start over.
