  New Revision: 64017

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=64017

  Log:
    thread.c (rb_thread_fd_select): remove unnecessary rb_fd_resize calls
    
    There's no need to resize each rb_fdset_t to match the size of
    the biggest one.  This can allow some small memory savings if
    watching several sets of FDs simultaneously.

  Modified files:
    trunk/thread.c
