# This is useful for finding memory leaks of the sort where a reference has
# been accidentally kept to an object when it wasn't intended to be. It
# is particularly useful if the leaking objects contain strings. 
#
# You can enable it in config/environments/development.rb It then writes
# to log files in logs/memory_profiler*
#
# If you have :string_debug enabled, you might find this one liner useful. It
# compares the two most recent string dumps.
# strings `ls -1t *profiler_strings* | head --lines=1` |sort > a; strings `ls -1t *profiler_strings* | head --lines=2 | tail --lines=1` |sort > b; diff b a |less
