From http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-core/22727 in the "Mixing runtime libraries" section the claim that you can mix msft c runtimes if

* If you call ALLOC or ALLOC_N, use xfree and not free
* Don't call sprintf or printf in an extension, instead use rb_f_sprintf/rb_vsprintf/rb_io_printf

...does it make sense to change these free's to xfree's (not libffi's dlmalloc?) in ruby-ffi?
