Here's a rewritten spamassassin plugin that has no issues with
SpamAssassin 2.50.  I ripped out all the attempt at speaking the SA
network protocol and just used spamc, which already knows how.
Unfortunatly this doesn't handle messages larger than the spamc size 
limit correctly.

  print WR $transaction->header->as_string, "\n";
  my $line;
  print WR $line while $line = $transaction->body_getline;
  $transaction->body_resetpos;
  close WR;
When spamc determines that the message is too large to be passed to 
spamd it passes the message to stdout immediately. Thus spamc will block 
 trying to write to its stdout pipe (since the plugin isn't yet reading 
from RD) and then the plugin will block writing to WR (since spamc isn't 
reading from stdin anymore).

  my $h = new Mail::Header;
  $h->read(\*RD);
  while (<RD>) {
        chomp;
        $self->log(10,"spamc returned body: [$_]");
  }
  close RD;
  waitpid $pid, 0;
This read loop would have to be interleaved with the write loop above, 
using select.
