# To do:
#
# Production
#
# - Ensure we detect and replay a failed txn involving blobs forward or
# backward at startup.
#
# Jim: What does this mean?
#
# Far future
#
# More options for blob directory structures (e.g. dirstorages
# bushy/chunky/lawn/flat).
#
# Make the ClientStorage support minimizing the blob
# cache. (Idea: LRU principle via mstat access time and a
# size-based threshold) currently).
#
# Savepoint support
# =================
#
# - A savepoint represents the whole state of the data at a certain point in
# time
#
# - Need special storage for blob savepointing (in the spirit of tmpstorage)
#
# - What belongs to the state of the data?
#
# - Data contained in files at that point in time
#
# - File handles are complex because they might be referred to from various
# places. We would have to introduce an abstraction layer to allow
# switching them around...
