Simplified `Component` by unifying duplicated code

[gmazzo]

In preparation for a fix proposal on a deadlock issue we are having, I noted this class was (intentionally?) fully duplicated.

To avoid making my changes twice, in NEEDLE_DYNAMIC and non-NEEDLE_DYNAMIC versions, I took some extra time to produce a unified version of it, by comparing its both final contents.
