[Pcsclite-muscle] How to recover from momentary loss of pcscd connection in psycard.

[Ben Mehlman]

Using the higher level classes of pyscard (CardRequest, CardService).. if
pcscd is shut down temporarily, it results in a ListReadersException.  I
would like to catch this exception, retry, and recover from it when pcscd
becomes available again.

I tried recreating the CardRequest but that wasn't sufficient to recreate
the connection to pcscd.
Is there a correct way to handle this?

Thanks
Ben Mehlman
