how can I call a non-threadsafe module sub from multiple parallel spawned child threads
There are no guarantees of course, but you're likely to have better results if you 'require' the problematic module within each child thread/process, rather than use/requiring it in the parent process - which causes its data to be copied to each child via thread cloning (which is how fork() is implemented on Windows perl).
