Inadequate (lock?) cleanup

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Start the applet
2. While reading the BeID card, interrupt the applet (refresh the page or 
click a link to navigate away or ...)
3. Next time the applet loads, it will get stuck in different ways.

What is the expected output? What do you see instead?
I expect the applet to read out the card.

Instead, I see the applet get stuck in a number of ways.  Each time the 
reader is attached and the eID card is inserted.  Each time, pcsctest(1) runs 
all tests just fine:

1. Not sure how to reproduce:

osName = Mac OS X
osVersion = 10.6.2
Detecting eID card...
Scanning card terminal: OmniKey CardMan 3121 00 00
could not connect to card: connect() failed
Please insert your eID card...

When I remove the card, this appears:
Scanning card terminal: OmniKey CardMan 3121 00 00

When I insert the card again, this appears:
Scanning card terminal: OmniKey CardMan 3121 00 00
could not connect to card: connect() failed


2. Reproduced by refreshing the page while authenticating (or causing an 
AJAX request on the page etc.):

osName = Mac OS X
osVersion = 10.6.2
Detecting eID card...
Scanning card terminal: OmniKey CardMan 3121 00 00
could not connect to card: Exclusive access has already been assigned to 
Thread Thread-30
Please insert your eID card...


When I remove the card, this appears:
Scanning card terminal: OmniKey CardMan 3121 00 00

When I insert the card again, this appears:
Scanning card terminal: OmniKey CardMan 3121 00 00

Next time I load the applet, this appears:
osName = Mac OS X
osVersion = 10.6.2
Detecting eID card...
