🚀 go-pugleaf

I'm working on an application that handles multiple data and
resource files, as documents. In order for my Revert
function to work safely, I have to somehow lock the files
while they're open so that they can't get moved; if
a file gets moved between the time that it's opened and the time
that Revert is called, havoc can result.

As it is now, I open the file (with FSOpen and OpenResFile), read
whatever information I need (with FSRead and GetResource), and then
close the file (with FSClose and CloseResFile). 

I need also to prevent a file from being opened twice, is there a way to
do this? Simply leaving it open doesn't seem to work, and I definitely don't
want to try to close the same access path twice -- doing so can have
horrible consequences...

Notice that the same considerations apply to an application that's 
runnning under Juggler...

Any help would be appreciated.
