Hello Michael,

I attempted to run it through Purify but after Purify sat there for 10
minutes doing nothing but exercising the CPU I gave up. This leak can
be exercised with the following test program:

use Sybase::DBlib;

$i = 0;

while (1) {
	printf "Attempt %d.\n", $i++;
	my $dbh = new Sybase::DBlib "xxxxxxxx", "xxxxxxxx", "xxxxxxxx";
	undef($dbh);
}

If you have a suggestion on how I might make purify work, let me know.
