Check "ps" to see who's running. You might have a runaway process.

I saw this sort of behavior once, when nothing showed up in ps. It turned
out to be the power management mode running wild; I had to reinitialize its
flash storage and reboot, after which things went back to normal.

Fixed in my latest private tree. I'll put up a new snapshot when I get back
to the states.

Ah yes.

There was a poprt of GNU "ls". That'd help, I suppose.

No, actually all the relative stuff is so that you can move the tree
anywhere. I don't want to change that. The only remaining wart is that
/vsta/include should have a matching /vsta/src/include.

Me, either. I wrote Hearts for MGR so I could bear to de-install Windows
3.1. :-)
