If you are running on Unix, you can limit the memory consumption by
using the limit or ulimit commands, depending on the shell you are
using. You would run one of these commands in the shell before
running IDL.

However, this may not have the desired behavior. Once the program
reaches the limit, any further memory allocations will fail and may
wreak havoc on your program. It won't just run "slower."

Good luck,
Craig
