+file system calls have units of bytes unless otherwise specified.
+functions returning handles or pointers use 0 to indicate error.
+see keys.txt for the return type of the "get key" system call.
the edx register of "start task" is a pointer to a null-terminated string.
a pointer to a readonly copy of this string is put into the new task's edx.
+ the esi register of the new task contains a handle to the caller's task.
+ the edi register is copied directly, and is intended to hold a task handle.
+ this task handle is who stdio ipc communication should be done with.
+ipc operations return 0xffffffff if the specified task doesn't exist.
+ "find unread ipc" system call returns 0 if there is no unread ipc.
invalid system call numbers change eax to -1, and have no other effect.
