Comment(by nickm):
Updated my branch. Fun stuff! I cut the gordian knot of "where to store
traces on crash" by saying "just put them in the log fd and on stderr."
For FreeBSD (and others?) we should look at linking libexecinfo, which is
supposed to provide the same information as the backtrace() functions in
<execinfo.h> on Linux/OSX.
For windows, we will need to look into [http://msdn.microsoft.com/en-
us/library/windows/desktop/ms680650(v=vs.85).aspx StackWalk64] for stack
dumping. I believe that the function to catch segfaults and whatnot is
[http://msdn.microsoft.com/en-
us/library/windows/desktop/ms680634(v=vs.85).aspx
SetUnhandledExceptionFilter], but I'm less sure about that.
