AFAIK, the GC only stops threads which are registered with it. This
can happen in
the following ways:
- threads started by the runtime are registered automatically
- threads registered using mono_thread_attach ().
- on unix, if an application includes gc.h, the header file will
() etc. with gc specific versions which register threads
- on windows, the gc registers all threads automatically.
Under what OS you experience this ? BTW, the problem with not
with the GC is that threads suspended by the GC could hold locks etc.,
so if another
thread tries to use these locks (like the malloc lock), it will be
Also, if one of these unsuspended threads tries to register itself or enter the
runtime while the word is suspended, various complex situations could occur.
