	After running AuthBy PAM for an certain amount of time...I get
	core dumps.  I don't see the correlation but I thought I might add
	that.  I haven't looked for leaks but there is something wrong
	with the way Radiator or Authen-PAM uses PAM...I use this same pam
	module for several other services that get used hundreds or
	thousands of times a day without problems.  But with Radiator or
	Authen-PAM I get core dumps often.

	This is on FreeBSD 4.5-RELEASE (which gets it's pam stuff directly
	from the Linux work).

	I tried it on other systems as well.  Don't know if it is related
	(probably not), but maybe there is a problem with Authen-PAM.
