- Fix detaching under some circumstances.
When truss is detaching from very active process it is possible to hang on waitpid(2) in restore_proc() forever, because ptrace(PT_SYSCALL) must be called before detaching, to allow the debugging process to continue execution. Also when truss called with '-c' argument, it does not print anything after detach, because it immediately exits from restore_proc().
To fix these two problems make detaching deferred, but then it is impossible to detach from a process which does not do any system call. To fix this issue use sigaction(2) instead of signal(3) to disable SA_RESTART flag for waitpid(2) that makes it non-restartable. Remove global variable child_pid, because now detaching is handled in context where child's pid is known.

Remove setpgid() call before executing child process.
Using a separate process group here is bad, since (for example) job control in the TTY layer prevents interaction with the TTY, causing the child process to hang.

When doing the initial open of the proc via procfs, complain if we are unable to open the /proc/pid/mem file. Otherwise doing a truss on a nonexistant pid makes us return success even though no such process exists.

Handle the case where we truss an SUGID program -- in particular, we need to wake up any processes waiting via PIOCWAIT on process exit, and truss needs to be more aware that a process may actually disappear while it's waiting.

Calls one or more of malloc(), warn(), err(), syslog(), execlp() or execvp() in the child branch of a vfork(). Changed to use fork() instead.
Some of these (mv, find, apply, xargs) might benefit greatly from being rewritten to use vfork() properly.

Change the ioctls for procfs around a bit; in particular, whever possible, change from
ioctl(fd, PIOC<foo>, &i);
to
ioctl(fd, PIOC<foo>, i);
This is going from the _IOW to _IO ioctl macro. The kernel, procctl, and truss must be in synch for it all to work (not doing so will get errors about inappropriate ioctl's, fortunately). Hopefully I didn't forget anything :).

Use the new PF_LINGER flag -- when this is set in a process' proc structure, said process will not have its event mask cleared (and be restarted) on the last close of a procfs/mem file for that pid. This reduces the chance that a truss-monitored process will be left hanging with these bits set and nobody looking for it.
This is the least-tested change of all of these, I'm afraid.
