You could craft a NetBSD binary that abuses the ELFNAME2(linux,probe)
test in src/sys/compat/linux/common/linux_exec_elf32.c so that the kernel
think it is a Linux binary. Of course if you use a syscall that does
not have the same number in NetBSD and Linux, you crash, hence I am 
not sure it could be useful.
