129ee966f8 Optionally use Python's flock instead of Ruby's 
Ruby first gained flock in 1.8.7, which is a problem since we're using
this lock utility in `vendor-install` in order to install a newer Ruby.

Fortunately, Python 2.3(!) has flock support.

9edf8eb1fe Check the lock directory is writable. 
And, if it isn't, print more helpful debugging messages.

Fixes #1456.

e3609b6fd4 Move LinkedKegs/PinnedKegs/Locks from Library. 
These don't make sense to be tied to the `HOMEBREW_REPOSITORY` but
instead should live in the `HOMEBREW_PREFIX` as they all relate to its
state.

1c27a75ca4 utils/lock.sh: remove redundant 'local' 2016-06-29 22:38:42 +02:00

8d64b6a02d introduce global lock directory (#337) 
Since #292, HOMEBREW_CACHE was moved to a per-user directory. This makes
it unsuitable to store global lock files on multiple users environment.

Therefore, introducing a global lock directory `/Library/Lock.d` to
store lock files from formula lockers as well as `brew update`.
