[PATCH v2 0/5] Speed up cache loading time

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

Compared to v1 [1], this is like a new series

 - git-read-cache--daemon is renamed to git-index-helper (easier to
   guess what it's for)
 - simplified locking mechanism on shared memory
 - UNIX signals are used for notification instead of UNIX sockets
 - Windows support (only tested with wine)

I think I'm getting closer to something that can finally have a chance
of merging. Still don't know how to write tests for this though.

Nguyễn Thái Ngọc Duy (5):
  read-cache: allow to keep mmap'd memory after reading
  index-helper: new daemon for caching index and related stuff
  index-helper: add Windows support
  daemonize(): set a flag before exiting the main process
  index-helper: add --detach
