# A dummy program that could be invoked by pam_exec.so, with the export_authtok

# To make PostgreSQL use this for authentication via PAM, make sure that it is
# configured with --with-pam (apt-get install libpam-dev first), and then
# create a file /etc/pam.d/postgresql (or other chosen service name) that
# contains the following:

Subject: [PATCH] Experimental spinlock changes on amd64.  Not tested.

Based on code review from mjg@freebsd.org, the LOCK prefix is redundant and
serves only to make the .text segment larger, and the fallback behaviour after
TAS() returns true should be to delay first, and then TAS_SPIN().

It may be that the logic in finish_spin_delay needs tweaking.
