(There are three running really, but two are idle.)
Well, the number of connections in CLOSE_WAIT or LAST_ACK drops from 17-18
to 6. CPU speed stays up. I found the delay in a terminal starting was not
from bash itself ("bash -c exit" takes around 0.002s) and not from rxvt (the
window pops up right away), so it must be from rxvt figuring out what to do.
That still happens. (How do I measure that? "time rxvt -e bash -c exit"
gives an unkillable process.)

Still is really. I'm just trying to figure out what's causing it, or
failing that, which subsystem's affected so I know where to look.
