kill and thisProcessID

["Nordlöw" via Digitalmars-d-learn]

I have a process that shall suspend itself using SIGTSTP or 
SIGSTOP.

My current plan is

     import std.process: thisProcessID, kill, Pid;
     import core.sys.posix.signal: SIGKILL, SIGSTOP, SIGTSTP;
     const thisPid = thisProcessID;
     // some call to kill()

but kill() needs a `Pid`

so

     kill(thisPid, SIGTSTP);

fails and constructing Pid cannot be done because

     kill(new Pid(thisPid), SIGTSTP);

errors as

     Error: class std.process.Pid member this is not accessible

What to do?
