"Facebook is, presumably, many separate components that don't depend on each other in any way"
Based upon the public statements about their build system and their revision control system and pain when trying to put it in Git I would be confident in saying that is false and that the source code is one big intertwined ball and no separate components.
Edit: Also based upon the way they treat public API which is always better than internal API even if they had internal separate components one could only imagine the horrors of api design (or lack of) you might find.
