MFp4 @1189139:

2013-12-15T22:58:09+00:00

Get rid of the msg_peek() function, which has a problem.  If there was less
data in the socket buffer than requested by the caller, the function would busy
loop, as select(2) will always return immediately.

We can just receive nvlhdr now, because some time ago we splitted receive of
data from the receive of descriptors.
