Well, that works great -- until you think about it a little. Function calls
resolving into the Linux libc are going to result in Linux system calls any
time they try to use kernel services (e.g. do I/O, e.g. print something); but
function calls resolving into the NetBSD libc will result in NetBSD system
calls. How, exactly, is the kernel supposed to decide which emulation to
apply to a system call issued by the resulting process?
