The idea on lcms-2 is a cmsDoTransform() is re-entrant and same
transform can be shared between threads. The locking happens only
if 1-pixel caché is being used, and in this case once per
cmsDoTransform() call.

So, you could try to inhibit caché (there is a flag to do so) or
process large chunks of data in each cmsDoTransform(). Probably
there is a room for improvement, but the basis are already in the code.
