Or, as a medium-sized answer: google for "python free threading". Removing the GIL is easy, but then the interpreter crashes in cases of simultaneous accesses to dictionaries, reference counters, etc. I also disagree with Martin Aliger's premises: # This degrades performance IMHO, mainly on server installations # (many web servers use python engine). This is just not true. On a single-processor machine, the GIL does *not* degrade performance. Instead, it increases throughput (and thus performance). On a multi-processor machine, you often use multiple operating system processes to serve request (e.g. in CGI or Apache mpm-prefork, or even the typical mpm-worker configuration). If you then have different processes running Python, they don't interfere with each other at all.
