``Syscall'' is another name for ``kernel trap.'' The syscalls for
Mach are completely different than the ones for Linux or other
The only portability provided by the Hurd is the Posix interfaces
defined by the GNU C Library. You should see if MzScheme has been
ported to Posix, and if not, suggest that they define a port that uses
`read (...)' rather than `syscall (... read ...)'.
That's a basic Unix portability guideline: don't use syscalls.
