but how much of that is the interpreter's fault?
I know I can't run typhoeus + thin on 1.9.2 on OSX as it reliably crashes every ten minutes and I have no clue on how to debug it, but it is not a problem with the interpreter, it's a problem with external libraries.
I'm not sure if those are both related to this or not, but I've had drastically more segfaults lately than in my past 6 years of ruby programming. It's getting pretty bad imo.
