Hmm, that's a possible workardound yes, but I'm curious about the
'offical' way
to handle this, or it is just not right to do an fdopen on socket fd's ?
It 
seems I can avoid the problem by setting the stdio buffer of the FILE *
to 0 bytes
with a setvbuf(), but I feel it's just a workaround, and not a real
solution...
