When bitcoind exits cleanly, it does not seem safe for the blockchain
to clean up the following hierarchy with rm -r ?
database/
db.log
.lock
debug.log
addr.dat
wallet.dat
And what about adding to the above list the following files when
bitcoind crashes:
__db.*
Is there an option to make bitcoind roll/flush the above files on
exit so they can be removed/ported?
No matter the answers, bitcoind should not be dumping core.
Bitcoin version v0.6.2.2-unk-beta ()

Use -detachdb if you want to detach the blockchain database files from the
database environment at exit. This was turned off by default in 0.6.0 to
speed up the shutdown process very significantly, and few people have a need
to manually fiddle with their blockchain database files.
