At the least, I think we need to redirect both stdout and stderr to a
file, so we can catch errors. The watchman patch uses warning() to
report errors, for example. And there is always a chance of die().

Then we need to report the errors back. I faced the same problem with
daemonizing git-gc, but I'm not sure if we can do exactly the same
here like in commit 329e6e8 (gc: save log from daemonized gc --auto
and print it next time - 2015-09-19)
