process exit test
Merge branch 'master' of /projects/instr/14au/cse451/groups/l/os161 into pexit
try to debug
current scenario
fixed proc->p_childlist and proc->p_childlist_lock types, commented out an extra call to proc_remthread() in thread_exit, and recopied the filename in fd_open, but still getting bugs with fork/waitpid/exit where waitpid returns -1 and the parent's exit crashes
