I'm testing a bit more (with the previous version, sorry) and got the 
following while doing a stream backup from a cluster that was at that 
moment doing a pgbench run with 1 synchronous standby.

mgrid@mg79:~$ pg_basebackup --xlog=stream -D /data -vP -h mg73 -U repuser
Password:
xlog start point: 15/720000C8
pg_basebackup: starting background WAL receiver
pg_basebackup: got WAL data offset 14744, expected 16791960424        )
5148915/5148026 kb g(100%) 1/1 tablespaces
xlog end point: 15/80568878
pg_basebackup: waiting for background process to finish streaming...
pg_basebackup: child process exited with error 1

The fetch variant worked ok.

mgrid@mg79:~$ pg_basebackup --xlog -D /data -vP -h mg73 -U repuser
Password:
xlog start point: 15/A2000020
5482029/5153458 kb g(100%) 1/1 tablespaces
xlog end point: 15/B51D0230
pg_basebackup: base backup completed.

I'm in total monkey test mode here, so I don't even know if I'm not 
supposed to do the streaming variant while other stuff is going on.
