Solaris fcntl bug 4700402 at the University of Queensland

  We were hit HARD with the fcntl lock problem.  It was taking users
10 minutes to log in to a PC (loading profile).  We were using 2.2.4
and 2.2.5, Solaris 8.  We dropped back to samba 2.0.6 to "fix" the 
problem - it now takes seconds to load the profile.

  I just checked the SunSolve site.  For bug report 4700402, they say it
is closed, and say the work around is to compile with --with-spinlocks.
