{frysk.proc.LinuxPtraceHost$PollWaitOnSigChld@1a6ab0,sig=Sig_CHLD} execute
frysk.sys.Wait pid 0 errno 0 (Success)

This is an attempt at starting an attatch.  sendAttach==ptrace(PT_ATTACH), then
it gets two SIGCHLD's but waitpid returns zip on both occasions.

Is this a child process or daemon process - might affect things.
