Ruby program that runs in miliseconds takes very long to record

[Franz-Fischbach]

A ruby demo program that completes in miliseconds takes 20+ minutes to record at which point the process was stopped.

Steps to reproduce:

1. Checkout the ui-tests/diff-view branch.
2. run `ruby test-programs/rb_big_lorem_ipusum/run_all.rb
3. run `ct run test-programs/rb_big_lorem_ipusum/run_all.rb

Expected result:
The the record should continue a bit longer than the pure ruby execution and codetracer should start after a couple of seconds.

Actual result:
Codetracer keeps recording the program for more than 20 minutes ( I did not test how long it will actually take )
