- Subject: Some GC measurements

From my app 5.1w4 with generational forced to 0:
GCSTEPMUL-> 2 8 16
GCPACE 82.3 80.0 78.0 worst-case FPS
2 4900 3900 3800 peak mem usage
4 86.5 84.7 85.1
5600 4900 4700
8 88.3 88.2 87.1
7800 6900 6900
Peakmem results do seem more stable (and a bit better)
than with generational allowed, though it's not really
a panacea.
With generational disabled, the 5.1w4 default for
GCSTEPMUL (8) looks reasonable, though a default GCPACE
of 8 still looks a bit high for a good peakmem (but is
thankfully runtime-tuneable).
