Ah, that explains it. With BUILD_TESTING off, you should be able to
load the Boost project into the VC++ IDE without much delay. By
consolidating library tests into a small number of executables (rather
than, *ahem*, Serialization's 400+ executable tests), we should
eliminate this bottleneck with the VC++ IDE *and* save a lot of time
and space when building/running Boost's regression tests.

Okay, done!

The patch is below; I applied it in tools/build/CMake.
