Description Henrik Andersson cendio 2011-11-17 11:05:58 CET 
pcsc lite has problem with threading and have a predefined way of
how this works, however it do not match the same behaviour using
MS PCSC, we do have a problem here because we are tunneling M$ app
into pcsclite eg. rdesktop -r scard for example, and pcsclite
should match the same behaviour which is does not.

This problem was found and can be reproduced using NetID and 
config option StateTimeout set to 10 which disables the poll
mechanism into infinit wait of state change.

Read more about this on bug #4011.
