only problem is that's not very efficient, and possibly wrong (for
packet oriented connections, such as UDP), as it can only read one
character at a time...

that buffering problem was the reason i implemented a getlines
primitive in the inferno std module which defines its own loop:

	getlines {
		echo line: $line
	} < filename

still, i'm not sure that shell scripts are the right place to be
implementing network protocols (although i can't say i'm entirely
innocent). dhog made a good suggestion:  that way you can run your
program on any system supported by inferno, which is a nice bonus.

 cheers,
