I believe that that is the case.

Keep in mind: this mess is cleaned up on the trunk; the threading options are 
simpler.  This is "legacy" now, on the v1.8 branch, and likely won't be updated.

The change that happened recently was that THREAD_MULTIPLE support was 
accidentally enabled by default on the v1.8 branch (which wasn't intended).  
The change a few days ago was to turn THREAD_MULTIPLE support off by default.
