It sends as much as it can when you call it. So if there's only 
12 bytes available when you send it with a 4096 buffer, it will 
fill the first twelve bytes (and return 12) so you can slice it 
buffer[0 .. returnedValue] to get the data.

If there's more available than the buffer will hold, that data 
will be held on to until next time you call receive. If 5000 
bytes come off the network, it will return 4096 the first time, 
then next time through the loop, it will return the remaining 904.
