There's a new version 2.7 of the native library LittleCMS released on
2015-03-18, which is supposed to improve multithreading.

On the homepage the news posted for version 2.7 is:

"Little CM2 2.7 released!  which improves multi threading, adds contexts
and a new locking plug-in type, among bugfixes and other minor features.
If you run lcms in multiple threads, upgrading to this version is highly
recommended."

I sent an email to the Author (Marti) and was mentiong a similar issue:

"I use the libcms2-2 version 2.6-3ubuntu1 library via Java IcedTea on
Ubuntu, and was just researching if there was a new version to fix ICC
embedded jpgs being resized with a purple tinge. (it seems to sometimes
be a problem upon startup on a 6-core multiprocessor server) "

Marti replied: "BTW, 2.7 fixes the issue on multiple threads."
