Log:      Fix an inifinite loop issue when the main process receives a  
SIGINT. If it
received a SIGINT, the signal handler would try to write to stderr "hey i'm
getting a SIGINT", but stderr was closed, which cause the it to generate a
SIGPIPE, which would go into the signal handler which would try to write
to stderr "hey i'm getting a SIGPIPE", which, since stderr is still closed,
would cause a SIGPIPE to be generated, repeat for infinity. This patch just
avoids writing the "hey, i'm getting a SIGINT" which avoids starting this
infinite loop of failed writes.
