I've found a bug in the scheduler: When a main thread finishes (e.g. returning from a ffi callback), the GC might be run before it is removed from the main_threads list. If a major collection happens, the thread will be garbage collected and the GC barfs when it updates the pointers in the main_threads list. This scenario is quite unlikely during normal operation, but when heap-profiling a HOpenGL program it leads to certain death after a few seconds. I don't know how to fix it in a clean way (I have no idea how my changes would affect the threaded rts or the other "ways") --- so can someone else please fix this?
