- Caching is still presenting issues with the new requirements for
rbyd trees, in this case the default bd, with 64 byte progs, revealed
and issue where rcache could become outdated when reading from disk
while ignoring what's in the pcache.
It assumes the pcache will always override the rcache, but this is not
true after pcache is flushed.
This didn't happen before as the rcache and pcache don't
interact while writing in the previous implementation. Because of
these new requirements the caching system probably deserves a
rework...
- The quick tests for sublinear space utilization don't work when
prog_size is > a byte, fortunately we should always have NOR-like
geometry under test, so we can limit these asserts to NOR-like
geometry.
- Lots of problems fitting these tests into 512-byte block_size
geometries, which is a bit concerning. This may be a larger change
from the previous implementation than expected. This may deserve more
scrutiny at small block sizes to see how things fit, since the
sublinear space utilization doesn't really kick in at this scale...
On the other hand it may just be that these tests are too aggressive
for 512-byte block sizes, since they don't yet do compaction, which
should help with padding/crc overhead...
