readline on Socket is broken

[fperrad]

the method readline of Socket PMC is broken

$ ./parrot examples/io/get.pir http://www.parrot.org/
** GET http://www.parrot.org/ ==> Null PMC access in get_string()
current instr.: 'parrot;HTTP;Response;status_line' pc 1149 (runtime/parrot/library/HTTP/Message.pir:558)
called from Sub 'parrot;LWP;UserAgent;progress' pc 936 (/home/user/checkout/parrot/runtime/parrot/library/LWP/UserAgent.pir:318)
called from Sub 'parrot;LWP;UserAgent;send_request' pc 262 (/home/user/checkout/parrot/runtime/parrot/library/LWP/UserAgent.pir:82)
called from Sub 'parrot;LWP;UserAgent;request' pc 406 (/home/user/checkout/parrot/runtime/parrot/library/LWP/UserAgent.pir:131)
called from Sub 'main' pc 38 (examples/io/get.pir:31)

the first readline on Socket PMC is in _receive_status_line (line 367 in file runtime/parrot/library/LWP/Protocol.pir) and returns empty data.
