ptrace (process trace system call) on Linux from D

Yes, that's more D-ish. In new D code I prefer the camelcased ones, but
there are cases where you'd like to use the original ones. it's up to! ;-)

I thing core.* (druntime) is the right place for _all_ bindings to libc.
But yeha, there are still some relicts in std.c.* of the good old days.

What do you meant by "D alternatives to wait() and fork() that could be
used with ptrace()". Maybe I don't understand your intention.
