synchronize a co-process with the controlling FMLI application
The vsig executable sends a SIGUSR2 signal to the
controlling FMLI process.
This signal/alarm causes FMLI to execute the FMLI built-in
which causes all posted objects with a reread descriptor
evaluating to TRUE to be reread.
vsig takes no arguments

The following is a segment of a shell program:
echo "Sending this string to an FMLI process"
The vsig executable flushes the output buffer
before it sends the SIGUSR2
signal to make sure the string is actually in the pipe created by
the cocreate function.
Because vsig synchronizes with FMLI, it should be used
rather than kill to send a SIGUSR2 signal to FMLI.
