Unicorn cannot be stopped (issue with setting unicorn_pid)

[paweldrozanski]

I've got problem with stopping unicorn. Every time unicorn:stop returns unicorn is not running..., while unicorn working just fine.
unicorn:start works correctly run once. But run twice (one by one) should start unicorn once and then report info "unicorn is running...". But it tries to run unicorn again.

According to that, there is some problem with setting unicorn_pid by unicorn.rake.

Same issue. I don't think this repo is being maintained.
