I'm sure it does suck under heavy load, although I suppose you could
increase the start time. But I wonder if that is the problem this
time? Modern machines are so damned fast they actually take real effort
to load. Actually, "make -j4" doesn't sound particularly heavy.
There's huge disk i/o in a make. Plenty of scheduling opportunities.
Obviously I only know what everybody else here knows; but with so many
recent posts suggesting a scheduling fault has been introduced, I'm
expecting it to be that.
