I care about whether or not journald will work reliable on an
unattended system. And from what I see there is no limit in the
mmap cache. This means that journald can potentially exhaust the
virtual address space. Will it happen? I don't know, time will
tell.

E.g. the test-mmap-cache.c does not test if the freeing of windows
(make_room) in case of a failed MMAP_FAILED. When was the last
time this code got tested/executed?
