I've heard several people reporting this, but have never seen it myself. If
you break and do "info threads" are the threads listed but asleep? You
could enable kernel instrumentation, and decode the instrumentation buffer
to determine what the kernel has been up to. You could even try setting a
breakpoint in the kernel at Cyg_Scheduler::unlock_inner which should catch
all thread switches.
