It looks like SystemTap + utrace will be the Linux equivalent of
DTrace. The first use of utrace (in -mm right now) is to make a
backwards compatible ptrace() that doesn't suck nearly as much and
muck with parent / child process relationships. utrace allows you to
do things like trace a tracing process for example and this is simply
not possible with the current ptrace implementation.
