WebThe key difference between fibers and kernel threads is that fibers use cooperative context switching, instead of preemptive time-slicing. In effect, fibers extend the concurrency taxonomy: on a single computer, multiple processes can run within a single process, multiple threads can run within a single thread, multiple fibers can run [1] WebA thread enters cooperative mode by calling Thread::DisablePreemptiveGC. This acquires the "lock" for the current thread, as follows: If a GC is in progress (the GC holds the lock) then block until the GC is complete. Mark the thread as being in cooperative mode. No GC may proceed until the thread reenters preemptive mode.
