My ulimit package exposes this API ([1], should finally submit it to
CRAN); unfortunately this very API seems to be unsupported on OS X
[2,3]. Last time I looked into it, neither of the documented settings
achieved the desired effect.

I found that setting RLIMIT_AS [1] works very well on Linux. But this
requires that you cap memory to some fixed value.
library(RAppArmor)
rlimit_as(1e9)
rnorm(1e9)
Error: cannot allocate vector of size 7.5 Gb
The RAppArmor package has many other utilities to protect your server
such from a mis-behaving process such as limiting cpu time
(RLIMIT_CPU), fork bombs (RLIMIT_NPROC) and file sizes (RLIMIT_FSIZE).
