Hmm. smbcontrol <pid> pool-usage just returns 0 with 3.0.20b here, so
that's not a lot of use.

The clients are Windows 2000 machines running in a workgroup. The samba
server is running security=user with passdb backend=tdbsam. There is no
domain running. The clients are mapping a drive and then just using it
throughout the day. They are run a DOS-based FoxPro database (AIUI) from
the mapped drive.
