-on application entry:
-  there is a 1MiB - 8KiB area mapped writable and not
-  executable with guard pages on either side, and rsp is
-  set to the top of that. all other registers are set to 0.
-
-the ARGC environment variable holds the number of arguments to main.
-the ARGV0, ARGV1, ARGV2, etc environment variables hold those arguments.
-
-for all system calls:
-  rax, rdi, rsi, rdx are in/out paramters.
-  rbx, rbp, rsp, r12-r15 are preserved.
-  rcx, rflags, r8-r11 are clobbered.
-
-interrupts (including the timer!) are disabled during system calls.

-stream result:
-   0 = success
-   1 = bad handle
-   2 = io error
-   3 = out of bounds
-   4 = does not exist
-   5 = not a regular file
-   6 = not an executable
-   7 = not writable
-   8 = not seekable
-   9 = socket id already used
-  10 = socket id not in use
-  11 = socket listener closed
-  12 = other end closed

-  framebuffer is always 32 bpp. use the encode color syscall
-  to encode colors. pitch is in dwords, not in bytes.
