Shutdown gracefully in 2 minutes or less ....

[johnsonjh]

then shutdown .... less gracefully.

Using our GoLevelDB fork, (and probably the latest upstream GoLevelDB too), panic is hooked so a graceful shutdown for at least the database is still attempted to avoid corruption.

I should probably make this 2 minutes because running a build with the race detector enabled - it's that slow.

Oh, Travis.

Once again, this is a false positive test failure, see Issue #128 and the fix/workaround is in PR #161
