I checked the GLADE sources and it's a semaphore, so the protected call
itself will not block on gethostbyname.
Anyway, the question remains: is it legal for a protected body to call
some imported subprogram that could block (in the pthreads sense of the
term) ?
Does someone know why the rule 9.5.1(8-18) is there at all ?
