Thank you for the information! I had forgotten it!
Yes, we used to have it, and it seems to be removed by the commit below:
http://git.kernel.org/gitweb.cgi?p=linux/storage/multipath-tools/.git;a=commitdiff;h=cad20ecf8919b2126ab6f4f793a1a738e9864f59
And probably the following thread is related to the commit.

Ben, Christophe,
Is that code still problem for current multipathd?
And what do you think about my proposal?
Thanks,
Kiyoshi Ueda
