The global allocator panics when out of memory rather than returning an
errors. In addition there are plenty of other places where we don't
handle allocation failure anyway. At some point in the future we should
systematically handle out of memory conditions, but until then let's not
pretend we do and get rid of the usage of the unstable allocator_api
feature that is unlikely to get stabilized any time soon.

Turns out the problem all along was that the ActivePageTable was never
dropped in usermode_bootstrap. So as soon as any other hardware thread
tried to do page table business, it deadlocked!

WIP: Stop using recursive mapping.
...
Note that this is very preliminary, and I merely got my already freezing
kernel branch not to triple fault, but I would probably apply this patch
to upstream.
What is changed here, is that rather than relying on recursive mapping
for accessing page table frames, it now uses linear translation
(virt=phys+KERNEL_OFFSET). The only problem is that the paging code now
makes assumptions that the entire physical address space remains mapped,
which is not necessarily the case on x86_64 architecturally, even though
systems with RAM more than a PML4 are very rare. We'd probably lazily
(but linearly) map physical address space using huge pages.
