[Bug 45546] Magic The Gathering Arena updater: Unity fork of Mono-runtime reports 'Fatal error in gc, GetThreadContext failed' ( suspension of Mono-managed threads sometimes exceed 100ms)

> Wine 's thread context retrieval mechanism relies on timely SIGUSR1 delivery to the target thread which in turn calls wait_suspend() to provide a suspend context on the server side

I'm also unsure why its implemented that way as MSDN states that
GetThreadContext is supposed to be called on an already suspended thread and
should not work on a running one
