If applications 207 access more memory than available, then the kernel must free memory in 208 the hard way: the OOM (Out Of Memory)-killer picks some processes to kill 209 in order to recover memory. 210 </p> 211<p> 212 <span class="bold"><strong>Boost.Interprocess</strong></span> has no way to change 213 this behaviour and users might suffer the OOM-killer when accessing shared 214 memory.

Posix based implementations use 1779 PTHREAD_PROCESS_SHARED attribute to place mutexes in shared memory, so 1780 there are no such problems. I'm not aware of any implementation that simulates 1781 PTHREAD_PROCESS_SHARED attribute for Win32.
