pcscdeamon.c sets up a signal handler for SIGUSR1 to call signal_reload.
But on Solaris (at least and it looks like HP too) the man pages say:

      If signal()is used, disp is the address of a signal handler, and sig is
      not SIGILL, SIGTRAP, or SIGPWR, the system first sets the
      signal's disposition to SIG_DFL before executing the signal
      handler.

Thus the first use of pcscd -H works, but the second time causes the deamon
to not cache the signal and end.

This looks like this has been in previous versions as well.
The patch has the signal handler reenable the signal.
Use of sigaction might be a better solution.
