-        I can't figure out how to check if a process is alive on Solaris.
-        This is what is wrong. Apparently the call:
-            os.waitpid(self.pid, os.WNOHANG)
-        does not work. It always returns with (0,0) whether the process
-        is running or defunct. This works:
-            os.waitpid(self.pid, 0)
-        but it blocks if the process IS alive, so it's useless for me.
-        I don't want to use signals. Signals on UNIX suck and they
-        mess up Python pipes (setting SIGCHLD to SIGIGNORE).
+        This also sets the exitstatus attribute.
+        It can take literally SECONDS for Solaris to return the right status.
