3/* Lots of system calls are trivial functions, so we build their source files
4   from a template.  New syscalls can be added simply by editing the
5   Makefile!

7   The system calls aren't necessarily reentrant.  If we were being used in
8   an embedded system they could be.  Reentrant syscalls are also used,
9   however, to provide ANSI C namespace clean access to the host o/s.
