Is anyone having issues using LibTIFF 3.7.X in a multithreaded
environment?  We are. Upgrading from LibTIFF 3.6.1 to the latest CVS
causes our application to hang when reading TIFF images using either
TIFFReadEncodedStrip or the RGBA Interface in a background thread.  The
first image read works fine.  But the second (in a different thread)
causes it to hang.

I don't have enough information yet to post a bug, but was curious if
there were known threading problems with CVS version of the library.
