* Adding intializers and changing macros
* Fix page-migration background thread on fork (#31)
* Fix page-migration background thread on fork
After falling off main in the forked child, all the children
try to join on on the parent's monitoring thread. This results
in a deadlock. Parent is waiting for the child to exit, but
the child is trying to join the parent's thread which is
signaled from the parent's static destructors.
Even with just one parent and child, due to copy-on-write
semantics, a child signalling the background thread to join
will still block (thread's updated state is not visible
in the child).
This fix creates background treads on fork per-child with a
pthread_atfork handler, ensuring that each child has its own
monitoring thread.
