[thread] tss crashes randomly

[t_schwinger]

Experienced with Mac OS 10.4.10 on an Intel-based Mac. The problem occurs with both 1.34 release and current trunk.

I had difficulties writing a minimalist program that reproduces the problem often enough to be catchable with a debugger.

The following gdb session illustrates the problem and was created executing the test 'trd_sp_singleton_threading' from the singleton archive in the vault ​http://tinyurl.com/35vlvb (a backport of Boost.FunctionTypes is needed to compile the test with 1.34 ​http://tinyurl.com/qaf5f - not needed with the trunk version):

Attempt of minimal reconstruction of the problem. Could crash it in a batch loop - crash too unlikely for debugging

[t_schwinger]

Maybe related to #1154. No exact duplicate - also happens with statically linked program.

I can't duplicate the problem, but the TSS code has changed since 1.34.1, so it might have been fixed.
