jmalloc is not being used

[grosser]

FYI just tried this and jmalloc is not active ... so kinda useless

ruby -r rbconfig -e "RbConfig::CONFIG['LIBS'].include?('jemalloc') ? puts('Ruby is compiled with jemalloc') : warn('JEMALLOC IS MISSING FROM RUBY')"

also FYI virtual apk packages help cleaning up apk add --update --no-cache --virtual ruby-dependencies foo bar + apk del ruby-dependencies \

Thanks for letting me know. I'm going to update the readme to deprecate this repo as I now recommend using the official ruby alpine images (e.g. docker pull ruby:2.4-alpine).

There is a pull request to add jemalloc support to the official images, although it looks like alpine is not an option due to a bug with ruby/alpine/jemalloc.
