 It turned out in #2222 that it's hard to test the fact that statistics
 number
 of currently running transfers is incremented when the transfer starts and
 then
 decremented after the transfer.

 We need a support to have a longer-running transfer. The proposal is to
 have
 larger zone and a client that starts the transfer, but does not eat the
 data
 off the TCP connection, so the buffers fill. We then can wait as long we
 need
 to check the statistics counters.

 This capability could be used for more things than just that, for example,
 we
 could try running more transfers in parallel.
