libmain: Clarify the lack of initLibExpr()

Browse source 
Quote

    Why not initLibExpr()? initGC() is essentially that, but
    detectStackOverflow is not an instance of the init function concept, as
    it may have to be invoked more than once per process.

Furthermore, renaming initGC to initLibExpr is more trouble than it's
worth at this time.
