Description

Cancellation requests don't yet handle using InterruptedException to deal with blocking operations. For example, if a thread is blocked doing I/O, or waiting for completion of write requests (via SendingAccountor), then we need to be able to interrupt it so we can continue.

This means both knowing what threads to interrupt, and for any relevant blocking sites to handle the InterruptedException correctly (see http://www.ibm.com/developerworks/library/j-jtp05236/). At present, most of these just log the exception and continue, effectively swallowing the exception, which is not correct.
