Windows WMI functions are called when creating or unlinking shared 
memory or message queues. Sadly WMI usage is causing a lot of problems 
and it's use will be removed. That means that shared memory and message 
queues will survive to reboots, but that behavior is allowed by POSIX. 
My tries to use kenel bootstamp and WMI to achieve kernel lifetime have 
caused a lot of problems, so it's better to go back to the old, 
pre-boost 1.39 behaviour than continue receiving bugs.

You can get the old behaviour commenting

#define BOOST_INTERPROCESS_HAS_KERNEL_BOOTTIME

in boost/interprocess/detail/tmp_helpers.hpp

Best,
