  "message": "qemu-thread: add QemuEvent\n\nThis emulates Win32 manual-reset events using futexes or conditional\nvariables.  Typical ways to use them are with multi-producer,\nsingle-consumer data structures, to test for a complex condition whose\nelements come from different threads:\n\n    for (;;) {\n        qemu_event_reset(ev);\n        ... test complex condition ...\n        if (condition is true) {\n            break;\n        }\n        qemu_event_wait(ev);\n    }\n\nOr more efficiently (but with some duplication):\n\n    ... evaluate condition ...\n    while (!condition) {\n        qemu_event_reset(ev);\n        ... evaluate condition ...\n        if (!condition) {\n            qemu_event_wait(ev);\n            ... evaluate condition ...\n        }\n    }\n\nQemuEvent provides a very fast userspace path in the common case when\nno other thread is waiting, or the event is not changing state.\n\nSigned-off-by: Paolo Bonzini \u003cpbonzini@redhat.com\u003e\n",
