I assume you're testing and encountering this result on a PDA, too.
I have never worked with one myself, but I assume that a platform
with more limited resources like that will naturally make more
conservative assumptions about the necessary size of buffers and
so forth.

In a simple test on MacOS X, I find that a stopped server can
wake up and process 100 or so datagrams that had been previously
sent to it, of sort of random length between 1 and 74 bytes.
I expect it could handle a lot more than that, and the same
would be true of any PC or server class Berkeley UNIX or similar.
Of course you would think the datagrams' size would have something
to do with it.
