[circle] IO error when starting text interface

[malcolm handley]

Based on Thomas' indication that the command line mode is less stable 
than the other interfaces I decided to try the text interface. Here is 
a log of my attempt:

grumpy:~/Projects/circle/Circle-0.40e malcolm$ python circle start
Making sure daemon is not already running...
 Circle daemon started.
grumpy:~/Projects/circle/Circle-0.40e malcolm$ python circle text
 Some random data is needed to generate a cryptographic identity for 
you.

OSError: [Errno 5] Input/output error

Although python does not show the line htat caused the IO error, line 
145 of circle_text.py is this:
            os.read(0,1)

Looking at the stack trace gives me the impression that this code is 
being run from the daemon and thus does not have stdin our stdout. 
Certainly, the branch of the daemon that lead to this call seems to 
have read its command from a non-stdin socket, which implies (to me, at 
least) that this is process really is the daemon. OTOH, the text about 
needing random data (which was written to stdout) did come through, so 
the process seems to at least have stdout.

Am I doing something wrong? Am I confused?
