#7875: BOOST_THREAD_THROW_IF_PRECONDITION_NOT_SATISFIED should not be enabled by
default

-------------------------------------------------------------+--------------
I just upgraded to Boost 1.52 on Windows using pre-built binaries and
encountered a problem. Because
BOOST_THREAD_THROW_IF_PRECONDITION_NOT_SATISFIED is enabled by default,
any code that uses thread::join() will throw an exception if the target
thread has already finished executing. Fortunately this was picked up by
our unit tests, but the new behaviour could lead to intermittent race
condition bugs that could be difficult to track down.
I've attached a patch (to be applied in libs/thread/build) which comments
out the BOOST_THREAD_THROW_IF_PRECONDITION_NOT_SATISFIED defines in the
jamfile. Failing that, could someone please explain to me why this feature
is enabled by default? It seems like a recipe for disaster. For example,
the fix for ticket #7668, which is attempting to work around a bug
introduced by this feature, seems to introduce a race condition.
