i submitted this bug report.
i just wanted to let people know that it has made a big difference to the 
stability of my system.

you have to rebuild qt (after changing two config files - just search for 
mysqlclient in the source release and change them to mysqlclient_r), so this 
is not much use to "binary only" users.

maybe gentoo is one of the few distributions which has not patched this up. 
who knows.

i'm sending this to the dev list in case it is of use to some people.
