data ExceptionInLinkedThread Source #

Exception from child thread re-raised in parent thread

We record the thread ID of the child thread as a String. This avoids an m parameter in the type, which is important: ExceptionInLinkedThread must be an instance of Exception, requiring it to be Typeable; if m appeared in the type, we would require m to be Typeable, which does not work with with the simulator, as it would require a Typeable constraint on the s parameter of IOSim.
