This has been sitting on the shelf, mostly due to my inability to find time to
work on it. It appears that we have working versions for x86, ia64, and ppc64.
Ports to other platforms should be just as easy. We see some performance
improvements, but we need to verify that improvements are as significant as
expected for cases like
probe kernel.syscall.*.return { ... }
Anybody who has time and inclination to pick this up, please feel free.
