	NO!  NEVER deallocate or reuse an IO request until it has been
returned by the device (and yes timer supports abortio, all devices must
"support" it, though not all devices will actually try to stop the io in
mid-stream.)  Normal abort is AbortIO();WaitIO().

	CheckIO only tells you whether the request hs finished.
