This is again unfortunately done in a later commit. Sometimes the review on these lines came at a later review just got corrected in that review... I does make things untidy I'll make bigger effort on this in the future.

Yes I am doing what your first line says. We surely can return directly but after we discussed it, probably not a failure because it's then harder to distinguish the two error cases: "process doesn't exist / has exited" and "we don't have permission && process not a child". We can return a None() (as in "dictionary get() returns null when the key doesn't exist"). The initial concern was code duplication (logging) but I guess it's better to be more explicit. Either way it probably doesn't hurt performance much. - Jiang Yan ----------------------------------------------------------- This is an automatically generated e-mail.
