Only to mention that POSIX Issue 8 has posix_getdents() that
gives application programmers a good tool for flexible buffer
usage ("none to many" dirents in one go, as you need it), as well
as lots of *stat*(2) avoidance possibilities.  This is a real
improvement when available, and i hope the world will go this
route, so that the only optional getdirentries() / getdents()
/ getdents64() / readdir()+stat() dances will come to an end in
the future.
