Could this modularization effort lead to a special compiled bitcoind
simulator that runs many virtual instances of a node on the same system
(possibly same process)? The simulator would cache crypto computation
results (ECDSA, SSH-256) to significantly speed up processing
transactions and blocks between the virtual nodes. The virtual nodes
would also need to share the same block data in memory when possible.
This would also require significant additional work to simulate the
network and possibly computational limits.
The transactions on the existing block chain could be replayed into
randomly chosen virtual nodes to help ensure any code changes would not
have caused problems with historic transactions. You could even record
all the messages for some time on many real nodes and use that as test
data for the simulator. Many other test programs could be devised to
quickly simulate other network activity.
This wouldn't completely replace the test network but could provide
greater and quicker confidence that code changes are safe.
