Newer versions of IDL support multi-threading. See Chapter 15 in the
5.6 manuals "Multithreading in IDL". It's in the "What's New" manual in
5.5, I think. I can't remember in which version it first appeared.

On my dual-processor Mac:

IDL> help, !cpu, /str
** Structure !CPU, 6 tags, length=24, data length=24:
HW_VECTOR LONG 1
VECTOR_ENABLE LONG 1
HW_NCPU LONG 2
TPOOL_NTHREADS LONG 2
TPOOL_MIN_ELTS LONG 100000
TPOOL_MAX_ELTS LONG 0

This translates as:
Vector unit present (currently Mac only)
Vector unit enabled
2 cpus available
use 2 threads when vectors satisfy these conditions:
minimum vector length, 100000
no maximum vector length
