the message is not intended for those loading from VFS file, but adding/building the VFS, because i have to warn people ASAP.
the warning loading is just a side-effect.
indeed, i think virtual-folders are usually abused, so i'm trying to make people aware of alternatives.
you may be aware and ready to wait for over a minute, but most people are not.
if i'm not aware of such thing, i will get nervous after half a minute.
actually i lowered the threshold to just 1000.
most people don't read documentation, so i'm trying to help all those who will use virtual-folders with no awareness.
