on platforms where the os uses proactor based i/o for vpn interface, tcp over lokinet is sloooooowwwwww af.

also... linux is the only platform that is reactor based i/o, literally every other one is proactor (android/apple/win32).

maybe consider making linux match this or make a platform independent way to convert proactor i/o to be reactor i/o in our event loop.
