There are run with Thread.critical=true.

------------------------------------------------------ Thread::critical=
     Thread.critical= boolean   => true or false
------------------------------------------------------------------------
     Sets the status of the global ``thread critical'' condition and
     returns it. When set to +true+, prohibits scheduling of any
     existing thread. Does not block new threads from being created and
     run. Certain thread operations (such as stopping or killing a
     thread, sleeping in the current thread, and raising an exception)
     may cause a thread to be scheduled even when in a critical section.
     +Thread::critical+ is not intended for daily use: it is primarily
     there to support folks writing threading libraries.

Hope this helps.
