Pre-rfork code assumed inherent locking of a process's file descriptor array. However, with the advent of rfork() the file descriptor table could be shared between processes. This patch closes over a dozen serious race conditions related to one thread manipulating the table (e.g. closing or dup()ing a descriptor) while another is blocked in an open(), close(), fcntl(), read(), write(), etc...
