No, nothing happened yet... as an alternative i can see two basic NetBSD
1) have a system call
msyscall_block([lwp,] from_addr, to_addr)
that blocks from the specified range all system calls. Easiest to add.
2) have a system call
msetemul([lwp,] emulspec, from_addr, to_addr)
that sets the emulation type for the specified memory range allowing say linux
libs to be linked to NetBSD libs etc... can/could also be used to insert a
system call block as `emulation'.
or we leave it as it is now...
