I have now checked in fixes for OpenThreads and DatabasePager, these
are merged with master, OpenSceneGraph-3.4 and OpenSceneGraph-3.6
branches.

Changes are:
   https://github.com/openscenegraph/OpenSceneGraph/commit/1224f400119e1e822bd83ef9a3f966bd8f90aaf9
   https://github.com/openscenegraph/OpenSceneGraph/commit/aa69f509337269a60ea3f22711a2190e733a84d8

Could you test this out with your applications and let me know how you get on.

If it looks good I'll create a 3.6.0-rc2 to wrap them up.

Thanks for pinpointing the bug,
Robert.
