I think the code that handles signal blocking is executed before teh code that determines if the signal's being ignored, which is executed in the kernel on behalf of the relevant process. The only thing I don't like about having the LDM ignore SIGCONT is that this would mean that EXECed programs would be in a non-standard execution environment. If such a program received a SIGSTOP, for whatever reason, it would never be able to restart and would have to be abnormally terminated. If the problem is primarily with the dcgrib2(1) decoder, then it might suffice to make decoders their own process-group leaders. This can easily be done by replacing the "setpgid(0, getppid())" with a "setpgid(0, 0)".
