Problems with URLAudio and leaking file descriptors on record

Every time we record an audio file with 1.2.14pl2, Bayonne is leaking 
the file descriptor (=leaving the file open). This appears to be because 
afSeek is failing, because URLAudio is not seeing the recorded files as 
Socket::STREAM.

I think this is because they are being opened by afCreate in ccAudio --- 
which of course has no knowledge of URLAudio.

The following patch adds in a URLAudio::afCreate which seems to fix the 
problem. Is there a better approach?
