Exception: getCurrentDirectory:getWorkingDirectory: resource exhausted (Too many open files)
"""]]

Exception: getCurrentDirectory:getWorkingDirectory: resource exhausted

fix process and FD leak Fix process and file descriptor leak that was exposed when git-annex was built with ghc 8.2.1. Apparently ghc has changed its behavior of GC of open file handles that are pipes to running processes. That broke git-annex test on OSX due to running out of FDs. Audited for all uses of Annex.new and made stopCoProcesses be called once it's done with the state. Fixed several places that might have leaked in other situations than running the test suite.
