 [Andrew, could you take this PR?  It's a problem on the sourceware side]
 
 This is a permission problem with /sourceware/snapshot-tmp.
 Here is the relevant part of log/update-cvs-version:

 After update-cvs-version fails to make its temporary directory, it keeps
 running in the current directory.  Remember, at this point there are *two*
 instances of update-cvs-version running, one for the head, and one for
 the branch!  They are both failing to create unique temporary directories,
 so they are both running in the same current directory and colliding.
 It looks like the branch always wins the collision; I don't quite
 understand that mechanism.
 
 Gerald Pfeifer reported the same permission problem here:

   Re: GCC snapshot generation and machine load
 
 He worked around the problem by creating a permanent subdirectory in
 /sourceware/snapshot-tmp with mode 2755.  Chris Faylor said that this
 is the right thing to do.  I looks like update-cvs-version needs a
 similar permanent subdirectory and a script change to use it.
