In an ideal word, some of us,
from R core, Jeroen, Kyrill, <one person knowing much about Windows>,
maintainer("microbenchmark>, ...
would sit together and devise an R function interface (based on
low level platform specific interfaces, specifically for at least
Linux/POSIX-compliant, Mac, and Windows) which would allow
something like your rlimit(..) calls below.
We'd really need something to work on all platforms ideally,
to be used by R package maintainers
and possibly even better by R itself at startup, setting a
reasonable memory cap - which the user could raise even to +Inf (or lower
even more).
I haven't found a Windows API that allows limiting the address space, only one that limits the working set size; it seems likely that this is the best we can get on OS X, too, but then my experience with OS X is very limited. mallinfo() is used on Windows and seems to be available on Linux, too, but not on OS X. -Kirill
