cmogstored 0.4.0 - minor improvements

* The kqueue code path now requires no more syscalls than the epoll
  code path on *BSDs.

* avoids malloc() usage after fork() (for iostat(1)).  This works
  around some malloc() implementations which fail to reinitialize
  malloc locks after fork().

* iostat(1) is no longer spawned for HTTP-only deployments.

* usage files are no longer created in HTTP-only deployments.

* FIONBIO + ioctl() is no longer required, we'll fall back to the
  slower (but POSIX) fcntl() equivalent if FIONBIO isn't available.

* Testers without native epoll or kqueue support, the the current
  stable branch of libkqueue (r549) should work as should future
  releases.

Users on GNU/Linux should notice no changes from the last release
unless they're using HTTP-only.

I look forward to hearing from our first GNU/Hurd users!
