New submission from STINNER Victor:
My colleague Fabio M. Di Nitto noticed that the memory allocation on the heap (PyMem_Malloc()) in select.epoll.wait() can have an impact on performance when select.epoll.wait() is a busy applicatin.
He proposed attached patch to allocate memory on the stack for up to FD_SETSIZE-1 events: see attached patch.
