This is a adaptation of some of the ObjectSpace.dump_all analyisis scripts found in Sam Saffron's article on "Debugging memory leaks in Ruby":
https://samsaffron.com/archive/2015/03/31/debugging-memory-leaks-in-ruby
The input files are also generated in a similar fashion that is described in the blog post:
io=File.open("/tmp/my_dump", "w")
ObjectSpace.dump_all(output: io);

The following is a way to determine where in the codebase bundler is stalling when fetching from external sources (rubygems.org, github.com, etc.). Use this as a way to determine where in the codebase bundler is stalling when it is happening without stopping the process or requiring modifications to the source directly.
bundler_trap.rb script and put is somewhere easily accessible (I use the home directory in my examples).ruby -I~ -rbundler_trap bin/bundle updatebundler has stalled. When it does, send the INFO signal to the process (CMD+t on OSX, and on Linux, it should be kill -sINFO pid, but you might have to use a different signal).
