#9355: boost::coroutine crash in base<void>::pull_coroutine_base<void> with
multiple threads

Comment (by Craig Hutchinson <craig@…>):

 A mutex based solution would be:
 {{{
 SYSTEM_INFO system_info()
 {
     boost::lock_guard<boost::recursive_mutex> lock(m_guard);
     static SYSTEM_INFO si = system_info_();
     return si;
 }
 }}}
 This isn't optimal though as there should be a way to only block on first
 entry to the function somehow.
