How to run Mono

You built Mono from git and now you want to run it. There are three approaches

Assume GIT_ROOT is an environment variable set to the directory where you build mono and it's your current working directory.

Run mono tests

If you added a new test to one of the usual places and you want to try it out

GC Safe, GC Unsafe, coop vs preemptive suspend and mechanics

I find the names gc safe/unsafe confusing.

"GC Safe": it is safe for the GC to modify this thread's view of the heap. "GC Unsafe" it is not safe for the GC to modify this thread's view of the heap.

If a thread is in GC Safe mode, it does not have any references to unpinned managed references. So the thread can keep running as long as it doesn't try to interact with Mono.

If a thread is in GC Unsafe mode it is doing something that would interfere with the GC - maybe it's accessing a heap object that the GC needs to move, maybe it wants to take the GC lock because it is trying to allocate. etc.
