now I can confirm mysql-server 5.0 is awfully broken on amd64, I've been
able to reproduce with a real fresh amd64 installation.

I had to get back to mysql 4.1.

wanna test ?
install server 5.0, install horde, try to load horde's mysql script to
create the database, enjoy the infinite locks on INSERT

advice : don't use it

since there is no debug symbols, I can't provide a usefull backtrace sadly.

I'll try to rebuild with debug enabled some time near.
