I think I've figured out what's going on.
First, here's the smoking gun: I changed the code as follows:
class myHandler(StreamRequestHandler):
def handle(self):
print '>>>>>>>>>>>'
while 1:
sl = select([self.rfile],[],[],1)[0]
print sl
l = self.rfile.readline()
if len(l)<3: break
print l,
pass
(Rest of code is unchanged.)
In other words, I select on the rfile object and added a timeout.
Here's the result when I cut-and-paste an HTTP request:
>>>>>>>>>>>
[<socket._fileobject object at 0x6b110>]
GET /foo/baz HTTP/1.1
[<socket._fileobject object at 0x6b110>]
Accept: */*
[<socket._fileobject object at 0x6b110>]
Accept-Language: en

<<<<<<<<<<<<
As you can see, the select call shows input available for a while (five
lines) and then shows no input available despite the fact that there is
manifestly still input available.
The answer is obvious: select is looking only at the underlying socket,
and not at the rfile buffers.
So... is this a bug in select? Or a bug in my code?
