Thanks for the new machine!

However I just noticed that "top" on the new gcc185 reports 0.0 total
user time even when half a dozen CPU-intensive compilations are
running, though "vmstat 5" gets it right. I'm using gcc113 (Ubuntu) as
a comparison machine to see if I can isolate the problem. I'm also
using gcc117 (OpenSUSE), but "top" only sort of half works there,
never reporting more than 50% at full load, and sometimes 0.1 or 0.7
when the rows add up to 400%.

So might you leave at least at least one of the older machines up, as
the only working example, until I manage to find the problem (or until
I give up!)

Incidentally, gcc113 is 95% full, though I guess that doesn't matter
too much at this point. The users in a position to help most (i.e.
with >10GB) are
