I think Windows support.
Signal support is actually easy because we can "hack" the IPI as
"suspend the VCPU thread+do work in the iothread context+resume the VCPU
thread" (the IPI handler doesn't longjmp).
Threading primitives support is tricky but not hard (there is lots of
code around, especially if you can make assumptions such as "always hold
the mutex while signaling a cond. variable").
