I should have put more information in my post:
Ubuntu 9.10, Core 2 Quad Q6600.

When loading a PEF image from a Pentax camera, the preview window takes
forever to draw, and performance is very variable and unpredictable.
UFRaw will just freeze periodically after drawing a few tiles.  This
also affects anything that causes the preview window to change, such as
exposure changes.

When OMP_NUM_THREADS is set to 1 as an environment variable, preview
redraws are fast and predictable in the time they take.
