I've managed to find a workaround. Not a great workaround, but it seems to let
me take advantage of all cores for OMP without penalty. I'll be running some
more tests on that.
The thread needs to call:
#include
omp_pause_resource_all(omp_pause_soft);
at thread termination (a hard
hread pool in the main process and still
have it used from the subthread.

The GraphicsMagick API has a thread arena and more general memory leak
somewhere in the GetImageDepth() API call, presumably a side-effect of
