Currently under Linux if you attach to a process whose process group id is not equal to its process id (such as the child process of a fork() call) the calls to waitpid() that pass -1*pid will return ECHILD since the pid argument refers to a process group that doesn't exist. These calls occur in Host::MonitorChildProcessThreadFunction() and the Linux ProcessMonitor.
Changing -1*pid to simply -1 or to -1*getpgid(pid) resolves the issue but it's not clear if this is the right fix as I'm unsure how other OSes deal with this scenario. Any thoughts? Thanks, Andrew
