-/*
-  a replacement for opendir/readdir/telldir/seekdir/closedir for BSD
-  systems using getdirentries
-
-  This is needed because the existing directory handling in FreeBSD
-  and OpenBSD (and possibly NetBSD) doesn't correctly handle unlink()
-  on files in a directory where telldir() has been used. On a block
-  boundary it will occasionally miss a file when seekdir() is used to
-  return to a position previously recorded with telldir().
-
-  This also fixes a severe performance and memory usage problem with
-  telldir() on BSD systems. Each call to telldir() in BSD adds an
-  entry to a linked list, and those entries are cleaned up on
-  closedir(). This means with a large directory closedir() can take an
-  arbitrary amount of time, causing network timeouts as millions of
-  telldir() entries are freed
-
-  Note! This replacement code is not portable. It relies on
-  getdirentries() always leaving the file descriptor at a seek offset
-  that is a multiple of DIR_BUF_SIZE. If the code detects that this
-  doesn't happen then it will abort(). It also does not handle
-  directories with offsets larger than can be stored in a long,
-
-  This code is available under other free software licenses as
-  well. Contact the author.
