- Improved async signal safety of read() particularly for longjmp() - Started adding cancel cleanup handlers for locks / etc on Windows - Make /dev/tty work better particularly for uses like `foo | less` - Eagerly read console input into a linked list, so poll can signal - Fix some libc definitional bugs, which configure scripts detected
