You can't put HANDLEs as members for classes shared in memory between
processes as they are void pointers only useful for the process that
creates them. Using native windows synchronization for process shared
synchronization primitives with POSIX lifetime semantics is not easy, no
project like APR or Cygwin has achieved this AFAIK.
