In cases where no typing echos and things really slow down, it's usually
because all of the clists are full (second bar in first group goes to
zero). This has always been due to a jabbering quasi-modem -- yanking the
plug on it restores it and the computer to sanity.

I'd say unhesitatingly that things got noticeably worse after
``upgrading'' from 3.51 to 3.51m. But I don't want to go back
because of the metermaid and a few other added features.
When I ran 3.51, systems would often stay up and running for 4-5
months. Now I'm lucky if things stay up for 2 months, and I
occasionally have to restart a dead or comatose process.

I guess we just have to wait for fixdisk 3 :-).
