Surely it is not. What would be the correct way to "un-fragile" the 
pdfsync definition of \emph? Would it be enough to say:
      \global\def\emph{{\protect\@PDFSYNC}\PDFSYNC at emph}%
or should the definition of \@PDFSYNC itself be altered?

As far as I know, the eventual aim (i.e., LaTeX3) is to eliminate 
fragile commands entirely, making it impossible to create them. Them 
guys sure are clever.
