After a failed file transfer (invalid resume request), the TransferController doesn't necessarily stop

[GoogleCodeExporter]

A 'resume' attempt on an outgoing file failed in the checksumming phase. This 
was caused by 
the file having the same name as an existing file on the receiver's end... even 
though it wasn't the 
same file.

The transfer was reported as 'canceled' on his side and 'failed' on mine.

My debug info (the sender):

The TransferController thread continued to run indefinitely as shown in the 
attached image.

Possibly related: joscar was using about 25% of the CPU continuously while 
idling (target idle is 
0%, obviously).  java.net.SocketInputStream.read() from 
FlapHandler.readFLAPHeader() was the 
by-far largest hotspot for useage, as you can see above.
