Sorry I must have not used reply to all.  Anyway, here is how I
trussed.  I had the user open a file, and then capture the system
calls made  with truss.  The fcntl appears blocking on a user file,
but I might be incorrect because I didnt really see which file the
file descriptor belonged to (the very first two lines of truss show
fcntl, no other information).  Either way, if this is blocking on tbd
file what possible recourse I can apply?  Thanks for your help.
