A nitpick:
FallbackAllocator!(InSituRegion!..., ...) can be faster by
defining a specialized allocator as a Region, which is
initialized with the slice of a static buffer, and once that is
filled up, a new buffer. This avoids a conditional branch in
FallbackAllocator (we'd be reusing the same branch that checks
for a full buffer and returns null in Region). This combination
will likely be used often so it might be worth optimizing this
use case, but OTOH the FallbackAllocator conditional branch will
likely be subject to good branch prediction, so at least on x86
the gain might be minimal.
