The current default garbage collector parameters request a doubling

I may be wrong, but I interpret the manual description of 'pause' as
meaning that the collector merely doubles the allocation threshold where
a new collection will forcibly take place. I can't find sbrk() in the code.
Is there a check for failed allocation due to RAM exhaustion?
Anyway, as I said last week, I'm not sure I really understand how this
mechanism works. To avoid the risk of memory overrun in an embedded
system, I ended out checking allocation level periodically with 'count'
and forcing a gc at a fixed threshold, then later checking it again
(suggestions for a better way are welcome).
