Not so. Linus has on several occations argued *against* moving a
certain facility to user space. Linus' opinion is that what can be
done WELL in user space, should go in user space.

Oh, by the way, for whomever was compaining about the lack of a "pure"
interface to the syscall, I suggest reading the rationale to POSIX.1,
which explains why the user shouldn't care about whether or not the
implementation in question uses a system call or a library call.

On Linux, for example, creat() is a library function that calls
SYS_open. On UNIX, it is a system call. Noone cares.
