Hi,
On linux if a program using the pcsc-lite client library (1.4.0) calls
another program via fork() and exec() then the child process inherits
a gratuitous file descriptor pointing at /var/run/pcscd.pub
This can easily be fixed by adding the close on exec flag to the file
descriptor when it is first opened.
