If at all possible, this code should be switched to use get*by*_r, or 
in the gethostby* cases, perhaps getaddrinfo and getnameinfo.  Marking 
it as a critical section for Guile won't prevent some other thread that 
is doing no Guile stuff at all from calling gethostbyname or whatever 
around the same time.
