I consider disabling the revisiond process a “hack“ and not really an option, as users may rely on this OS X feature. The daemon might also get re-enabled by an OS X update anytime.

This leaves you with the option to disable the core.trustctime setting, which I believe has no noticeable performance drawback for most or maybe all Git users.

If you are sensitive about the performance, perhaps a third option would be to make an alias for affected commands, especially for rebase:

_rebase = "-c core.trustctime=false rebase"
