Under e.g., Digital UNIX, this problem may also be artificially imposed on
a process by software limits on memory use, maintaned by the user's shell - e.g.,

unix> limit
cputime unlimited
filesize unlimited
datasize 131072 kbytes
stacksize 2048 kbytes
coredumpsize 0 kbytes
memoryuse 90200 kbytes
vmemoryuse 1048576 kbytes
descriptors 4096

The limits may be changed by e.g.,

unix> limit datasize 1024m

which gives the child processes an allowed data size of 1 Gbyte.

I'd also like to point out the use of the coredumpsize, which disallows
any core dumps when set to zero - how often do you actually *use* those
humongous files, anyway....
