 When hexl-find-file finds a file, which is already

 I wonder, if it should be disabled (*before* the
 buffer is hexlified, to save time. Deactivating
 font-lock in a hexl-mode-hook will not avoid the
 unneccessary font-locking.)
 
 If font-locking is disabled by hexlify-buffer, it
 will still be off, if you leave hexl-mode via
 hexl-mode-exit. Would this be a problem?
 
 If someone uses customized font-locking for hexl-mode
 (as I do sometimes), how can the original font-locking
 be restored after hexl-mode-exit? 
I think that this is a more general problem with changing the major
mode, particularly when changing to or from a "special" mode. 
change-major-mode-hook is probably run too early on for this purpose. 
It would be useful if there was a hook which was called after the
corresponding function had completed; but, AFAICT, there isn't one.
