[PATCH v2 0/5] support fiddle for Linux-only syscalls

[Eric Wong]

fiddle can be used as an alternative to sleepy_penguin, since
sleepy_penguin requires development headers and a compiler to
install, and fiddle is bundled as part of Ruby.  sleepy_penguin
can still be faster, though, so we continue supporting
sleepy_penguin.

Eric Wong (5):
  pipe: avoid loading sleepy_penguin
  provide fiddle-based eventfd implementation
  buffer: replace sleepy_penguin with fiddle
  watchable: use fiddle for inotify support
  doc: remove most recommendations for sleepy_penguin
