----------------------------------------------------------------
[~ashutoshc], if file system cache is enabled
(fs.<scheme>.impl.disable.cache=false) then getFileSystem() should return fast.
We don't call it twice in the loop, if we enter the first _if_ we _continue_
and don't call the 2nd one. If we enter the second _if_ we don't call the first
one.
