Another problem as occurred while trying to use this code.   I've been
getting a stack error so decided to use rdebug to see what I could
find out.  During that process, I got this:

Call #1 :: ruby_stack_check = 0 / ruby_stack_length = 2691
Call #2 :: ruby_stack_check = 1 / ruby_stack_length = 35706191
Tracing(1):./sample.rb:11 print "my_connect:\n"
my_connect:
Tracing(1):./sample.rb:12 print "   + hostname: #{hostname}\n"
   + hostname: localhost

The interesting thing is that the program didn't stop...it continues
to run.

The function at hand is supposed to be a registered callback.

Any ideas on what I might do to figure this out?
