Is ratrace usable on native Plan 9 (I understand it's in use on 9vx
thus far)? I don't see a /proc/n/syscall file for any of my processes;
is there some kernel patch for this?
Thanks,

Glibc /bin/date on Linux runs around 140 system calls. A quick pass
with ratrace shows that plan 9 /bin/date has 10.
The conclusion is clear: plan 9 date has way too much overhead. It's
1/14 the number of system calls of Glibc; why's it so big?
A quick pass on getpid() fixes the problem:
