Building NetBSD-current/i386 on a Debian 7/amd64 host,
the disk partition holding the build destdir fills up
with a huge destdir/usr/share/info/dir{,.lock,.tmp}:

This does not seem to happen on NetBSD build hosts.

I'm guessing this has something to do with the recent introduction of
the sortinfo tool.  I tried running the Linux nbsortinfo tool on a
well-formed info directory file from a native NetBSD build, and the
output looks corrupted:

  gumbo ~ $ head -30 /run/shm/dir
  This is the file .../info/dir, which contains the
  topmost node of the Info hierarchy, called (dir)Top.
  The first time you invoke Info you start off looking at this node.

  File: dir,     Node: Top  This is the top of the INFO tree

    This (the Directory node) gives a menu of major topics.
    Typing "q" exits, "?" lists all Info commands, "d" returns here,
    "h" gives a primer for first-timers,
    "mEmacs<Return>" visits the Emacs manual, etc.

    In Emacs, you can click mouse button 2 on a menu item or cross reference
    to select it.
