Details
MakeFileInputStream in nsIFileChannel calls IsDirectory() on the main thread, at https://searchfox.org/mozilla-central/rev/b756e6d00728dda4121f8278a744381d8643317a/netwerk/protocol/file/nsFileChannel.cpp#298 . That's going to cause IO (ie a stat call, unless we have a cached stat result in the nsIFile instance already), based on code inspection of our *nix and Windows implementations for nsIFile::IsDirectory(), but it doesn't seem to show up in profiles at all.
