Logged In: YES user_id=119306 Thank you for pointing me to PEP 7. I'll take a look at where I am amiss and fix it up. For the change in ceval.c, I took a look at gcc's x86 assembly output of the file, and noticed that the optimizer was altering the order of the busy flag test. Since busy is set from other concurrent execution (other signal handlers), changing the variable to volatile told gcc not to optimize accesses to the variable.
