Hmmm! I've noticed the 'do {} while EINTR' being a quite common practice in
a lot of similar situations. I've wrapped the offending select in the
libwww-perl code and it has been working happily for two days. Thank you
very much!  I have also submitted a bug report to the libwww-perl's bugtrack
at sf.net, I don't know if they will include on new releases but I hope
so...
