Very strange.  When I attached strace, the cpu cycles used dropped
down to nothing.  Then, when I stopped pcscd and tried to restart it,
the process won't start up again.  I wonder whether strace somehow
caused pcscd to not stop cleanly?  I'll file a bug and post with the
bug ID.  Should I CC you inside the bug report?

strace -s512 -f -p $(/sbin/pidof pcscd)
