[Bitcoin-development] Manual file cleanup on exit, safe? [coredump backtrace]

[grarpamp]

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.
