shared_ptr
atomic_ptr
make_single

Nekotekina 8b6d615aa6 atomic.hpp: remove/deprecate incomplete notify features 
Notification with "phantom value" could be useful in theory.
As an alternative way of sending signal from the notifier.

Also fixed slow_mutex (not used anywhere).
 2020-11-26 06:31:36 +03:00

 2020-11-24 13:20:40 +03:00
Nekotekina ab248e170c vm_native.cpp: add MADV_HUGEPAGE
