use exit codes to denote success/failure

[C-Otto]

• 0: rebalanced some amount
• -1: didn't rebalance
• -2: generic error
• -3: didn't find route (after several attempts?)
• ...

This is already implemented for the main use case: success vs. failure

So, commenting here instead of bugging you on plebnet.
I keep getting exitcode!=0 occasionally, even if rebalance succeeds.
Finally supposing it was because I prepended timeout --preserve-status -k 5 120 to the rebalance command, and maybe the 5s kill happened too soon before rebalance-lnd had time to graciously exit, and was prevented to communicate a 0 exit code even if lnd kept working and completed the circular route.
So now I use 30s kill timeout, but I still get fake failures on exit code from time to time.

Do you reckon even 30s is not enough, or is there something else I can do to help you debug this?

Payments can be stuck for hours...

There's probably no solution to this, even adding a --timeout <seconds> to rebalance-lnd will hit the same wall, leaving possibly a payment hanging as failed that instead could succeed later on.
