Description of problem:
ruby aborts with even the simplest hello world rails app.
Try a simple "hello world" rails app, from any intro rails book, and reload a
few times.  It won't take long before you get an "abort()".
Then I tried a goldberg generated site (with sqlite3) and got the trace below. 
So maybe this is really two bugs.

Version-Release number of selected component (if applicable):
ruby-1.8.6.230-2.fc9.i386
rubygem-rails-2.0.2-2.fc9.noarch

How reproducible:
Always

Steps to Reproduce:
1.Create a "hello world" rails app
2.Load and reload a few times
  
Actual results:
You'll get a simple Abort eventually.

More complex rails apps may result in something like the following:
