Just thought I'd mention that this has been fixed for a few weeks
now. That is, los0-gc is able to work with semi-spaces of practically
any size, and the default action of the los0 image should be to split
the machine's available memory in two and do stop-and-copy between
these parts. (Although still there's no decent code to detect memory
other than the ancient bios method, which is restricted to 64 MB, but
this should be trivial to fix once the good detection mechanism
identified). And allcating buffers of a few megabytes should therefore
be unproblematic now.
