Boost unit test "sync_pq_multi_thread_p_lib.exe" hung in thread library

[seaheart_2006@…]

We tried buid and run unit test for Boost. There is a test "sync_pq_multi_thread_p_lib.exe" hung in thread library. This issue can be repro from master branch revision ad85f23​https://github.com/boostorg/boost/commit/ad85f23f7200cd7b99291b672c18ce69e5e1758c. Could you please take a look at this? Thanks in advance!

Reproduce steps:

1. git clone -c core.autocrlf=true --recursive ​https://github.com/boostorg/boost.git D:\Boost\src
2. Open a VS 2015 x86 command prompt and browse to D:\Boost\src
3. .\bootstrap
4. .\b2 headers variant=release --build-dir=..\out\Release --address-model=32
5. .\b2 variant=release --build-dir=..\out\Release --address-model=32
6. .\b2 -j4 variant=release --build-dir=..\out\Release libs\thread\test

Expected result: All tests passed

Actual result: Test "sync_pq_multi_thread_p_lib.exe" hung. I have to kill the process manually.

I believe this is fixed in develop by ​https://github.com/boostorg/thread/commit/39c23ddf5a3082d76ebda107dce02fb86e948cd4
