Some of the system calls are wrapped in libc first - for example,
read() is a wrapper for pread() - but on average, system call foo is
connected by a trap through a table defined in
/sys/src/9/port/systab.h (generated automatically from
/sys/src/libc/9syscall/sys.h) to a routine in /sys/src/9/port/sys*.c
called sysfoo(). A few later system calls appear in files not
beginning with "sys", a regrettable lapse.
