Public bug reported:
In case of the following scenario:
1. PAM configured to run auth and session with pam_exec scripts synchronizing
via SIGUSR1
2. Using GDM as the login manager causes SIGUSR1 never reaches the target
scripts.
Workaround:
a) Use SIGUSR2 in the scripts.
b) Comment out block_sigusr1() call in daemon/main.c.
