NAME
pidwatch - Run a command and if another PID exits, kill the command
SYNOPSIS
pidwatch [--cd I<cd>] --host <host> --pid <pid> [args....]DESCRIPTION
Chdir to the specified directory, if specified and possible.
Run the arguments as a command in the foreground. When the foreground process exits, return its exit status.
In the background, watch the specified pid on the specified host. If pidstatd is running on the specified host, and the specified pid goes away, kill the foreground command.

system("rsh \$remote_host pidwatch"
." --cd \$ENV{PWD} --host \$ENV{HOST} --pid \$\$"
