You can write thread safe OR thread unsafe code in masm like anything else, it depends entirely on what you want to write. There is no point in all code or a given development environment being fully thread safe as a vast number of tasks don't require it. Where you need re-entrant code, you write it accordingly and maintain the appropriate data structures on a per thread basis or you can mess around with thread local storage if you like but it comes back to what YOU write, not the development environment that you write it in.
