Please (if not already done):

1. Remove both instances of
     self->num = fd;
   in ei_connect.c so it is possible to use process id for transaction
   id to avoid the 6 + 1 = 4 scenario presented at EUC.

   Anyone wishing to preserve the old behavior can still set the value
   in their own code before calling ei, although I haven't thought of
   a reason to do so.

2. Also fix the select statement in ei_connect.c.

A patch against R9C-0 showing both suggestions is here
