 see this ticket:
 https://svn.boost.org/trac/boost/ticket/4010

 however this problem is much worse: when running in a VM (eg: parallels)
 repeated calls (without waiting) to get_system_time_of_day_information()
 return DIFFERENT numbers in the info.data.liKeBootTime field.  because of
 this, shared memory always fails.

 current "workaround" is to do this:
 info.data.liKeBootTime &= 0xFFFFFFFF00000000;
 after every call.
