Killing the daemon shouldn't have direct impact on umount of the map,
unless all the paths for that map go offline. If every operation goes in
parallel (with my understanding of the new gen init services like upstart
and systemd), and iscsi sessions get dropped before the umount, yes, you
definitely will run into the hang situation.

Again, the hang situation depends on how your multipath policy is
configured.

It is hard to make out what might be the cause from just the english
explanation. Perhaps the multipath maintainer here can translate this to *Steps
To Reproduce* and then investigate it further.
