I had four failures attempting to build on windows. However, they were
atypical in that the build stalled out and would not continue, rather than
producing an error.

The last items in the terminal before stalling out was something like:
        1 file(s) copied.
        1 file(s) copied.

It seemed to be generally in wave, however one time it failed in log. This
example shows the problem during msvc-14.0, but I believe I also saw it in
14.1 one of the times. I had experienced something similar during the beta
build, and after succeeding I was unable to reproduce it on the same
computer, somehow related to caching? Very weird, and I don't think we
should release while this is ongoing.

On the fifth try, I was able to get a good build for all versions of visual
studio I was attempting.

toolset arch compile Link Execute
msvc-10.0 32 X X X
msvc-10.0 64 X X X
msvc-11.0 32 X X X
msvc-11.0 64 X X X
msvc-12.0 32 X X X
msvc-12.0 64 X X X
msvc-14.0 32 X X X
msvc-14.0 64 X X X
msvc-14.1 32 X X X
msvc-14.1 64 X X X
msvc-14.2 32 X X X
msvc-14.2 64 X X X

Compile means that the b2 command completed without errors
Link means that visual studio was able to link a sample executable to a
library (libboost_thread-vcXXX-mt[-gd]-1_XX.lib) generated
Execute means that the linked program executed without errors.
