Summary: Use signal to show stacktrace of a Ruby process without restarting it documentation files

Description: 

Use signal to show stacktrace of a Ruby process without restarting it
documentation files.

In short: SIGQUIT of Java VM for Ruby.

Server applications (like Rails apps) cause performance problems, deadlock or
memory swapping from time to time. But it's difficult to reproduce such kind of
problems. sigdump makes it possible to get information from a running process
without restarting. Just sending SIGCONT signal will dump backtrace and memory
profile to /tmp/sigdump-<pid>.log file.

sigdump dumps following information (see also Sample output):

* Backtrace of all threads
* Number of allocated objects per class
* GC profiler reports if GC profiler is enabled (GC::Profiler.enable is called)
* Stacktrace of Java threads for each Ruby threads if the runtime is JRuby
