ErrPipeReadWrongSignal occurs if we read unexpected signal from pipe between parent and forked processes.

ErrPipeWrite occurs if we can't write to inter-process pipe (that we use for forked and parent processes synchronization upon SIGHUP handling).

ErrShutdownTimeout occurs if we can't perform correct exit from realMain function (when we can't stop background goroutines used to handle system signals).
