Mspec seems to be returning the wrong exitcode when used from irtests.bat. The 
first mspec command which runs the core tests has failures in Module#autoload 
but sets errorlevel to 0. And the second command has no failures but sets 
errorlevel to 1. When I try out some mspec commands manually, the errorlevel 
does seem to be set correctly. So I am not sure why this is happenning. Once 
Jim pulls in my changes, lets see if others get the incorrect behavior or not, 
and then we can decide what to do. Jim, if you have any ideas of what might 
affect the exitcode, let me know...

About RubyArray.Equals(object)/GetHashCode, I will be changing it in a 
subsequent change to have it do reference equality.

Re RubyArray.Equals(object)/GetHashCode: is it desirable to use value equality 
here? These methods are only used from .NET libraries - e.g. if the array is 
added into a dictionary as a key. Unless RubyArray is bound to a runtime its 
.NET hash/equality implementation won't be the same as Ruby's (ie. calling 
hash/eql? one each element). Wouldn't be better if RubyArray behaved like 
List<object> in .NET collections?

http://github.com/shri/ironruby/commit/7f3d766216c2fa533e208ac2a44b8de39cb03f7c

*         Fixes Array#hash to work with recursive arrays

*         Also updated ArraySpecs.recursive_array to produce a cycle of length 
3. Previously, it was doing "a << a" multiple times, but this does not increase 
the length of the cycle above 2. It just increase the number of cycles. This 
change required an update to many files.

*         Also added a new ArraySpecs.recursive_arrays function which should be 
used when dealing with two arrays (comparisons, merge, etc). I have only used 
it in equal_value_spec and eql_spec for now...

*         Also removed entries from critical_tags.txt since recursive hashing 
and comparison now works.

http://github.com/shri/ironruby/commit/a011753ebab46652992a0d82a94437811f456381

*         Changed irtests.bat to not use "mspec -V" (unless you are using 
"irtests -par") which was causing very verbose output

*         Changed irtests.bat to only use two "mspec" tasks so that "irtest 
-par" will spawn fewer processes.

*         Changed IronRuby.Tests.exe to show dots for each test instead of 
printing a new line which is very verbose

*         Changed irtests.bat to continue running tests even if previous test 
task failed. It remembers the failed results and prints the summary at the end.

*         Added ruby19.bat so that "mspec -tr19" runs with Ruby 1.9. It 
requires you to set RUBY19_EXE to point to your copy of the 1.9 version of 
ruby.exe

Thanks,
Shri
