that? Of course, I can manually read data from the socket until unpack()
stops complaining about a lack of data, but that sounds rather inelegant.

Any better suggestions?

Read until you get the required bytes; use the size attribute.

The struct module has a function called "calcsize", eg:

>>> import struct
>>> struct.calcsize("<H")
2

That will tell you how many bytes to read.
