 I was seeing memory leaks in Samba on my home server.  (simple setup
with 1 win2k client.)  I was wondering why my machine was feeling
slow, and I saw that smbd was using all my RAM:  300MB RSS, > 600MB
virtual size, on my 512MB PIII 500MHz.  And my small swap partition
was mostly full.  This is after only a week of having Samba running,
and this machine normally goes for months without reboots.  This is a
showstopper bug for me, so I'm heavily in favour of updating stable.

 Are there configurations where it doesn't leak, or are modern servers
supposed to have so much RAM and swap that it doesn't matter?  The
latter is IMHO not a good enough argument to justify leaving it unfixed.

 I compiled Samba packages for myself with bug_520794.patch (thanks
Christian).  I'll keep an eye on it to see if it's still leaking.
ping me in a week if I forget to update this.
