You cannot use any approach that requires the method code to be modified after
it is first generated. It isn't thread safe: what if another thread is
executing the method while you are modifying it? It isn't even thread-safe
for the thread that you are suspending: if it is suspended while the thread
was in the middle of executing the NOP, then it will be in an unknown state
when resumed.
Outputting abort check instructions on every backward branch is OK with me, as
long as you only do it in programs that use Thread.Abort. This can be
detected by the loader (any assembly with a MemberRef to Thread.Abort is a
candidate).
Cheers,
