I don't understand this.  It sounds like cause for a bug report.

 PJ> Handlers aren't involved until I/O is attempted, AFAIK.

I believe the operations listed under Info (elisp)Magic File Names
accurately reflect the code.  If not, please make a bug report.

[I can speak for Emacs 20 and Emacs 21 development code.  I recall
that XEmacs appeared to have some problems connected with file name
handlers, but I don't recall what they are.]
