If you're under memory pressure at the wrong instant (such that lvcreate
or its shared libraries are paged out of memory), or the code is
restructured such that it happens to need a new page from its binary or
shared libraries at that instant, you'll deadlock because the source
(i.e., /) is SUSPENDED during snapshot creation.
