* Duplicate console output of services from log noise to error msg.
* integration: Store stdout and stderr chans in the ServiceInstance (Also ensure logs are kept for nginz)
* Stronger signal to backend processes when terminating. (The timeout before this change wasn't effective; waitForProcess blocks beyond the timeout if the process doesn't terminate.)
* Make default log level in ModServices easier to change.
* shouldMatch argument order matters for error message!
* Use lifted-base (instead of re-inventing it).
* Use timestats library to dig into where the timeouts are caused.
