VBoxManage.cpp@ 47348

Last change on this file since 47348 was 46649, checked in by vboxsync, 12 years ago
Forward ported r85941 and required build fixes (Main: Implemented new event queue to separate system's native event queue and our own. Also, XPCOM is not needed for handling our own events. On Windows this also fixes the system's queue quota limitation).
Property svn:eol-style set to `native` Property svn:keywords set to `Author Date Id Revision`
