Every time I see something like this (turn function calls into a network call), I reflect fondly on the list of fallacies in distributed computing [0]. These are issues that largely have to be handled in an application-specific way, and cannot be solved in the general case.

This list alone has saved me many late debugging nights, just by not making or using systems that ignore the list.
