I find that urllib fails on ftp if:
- I start more than 1 transfer, each in its own thread
- I let those finish
- I again start more than 1 transfer, each in its own thread
One of the latter xfers will fail with:
  [Errno ftp error] 200 Type set to A

I have attached sample code that demonstrates the problem.

Notes:
- I have seen the problem on more than one ftp server, using 
different sets of sample files.
- An explicit ";type=i" suffix on binary file URLs does not help. I have 
not tried text files with explicit "type=a".
