Some of my `hangs' stopped at this point too.

    $ cvs -f -z 3 up -dP
    ...
    cvs server: Updating src/utils/tfmtodit
    cvs server: Updating src/xditview
    cvs server: Updating tmac

strace leading up to this is

And then it stops.  I've let it sit there for 40+ minutes.

I've tried a checkout from scratch instead of an update.  Similiar
behaviour.

    ...
    U groff/tmac/tty-char.tmac
    U groff/tmac/tty.tmac
    U groff/tmac/www.tmac

    write(5, "/.cvsignore/1.3/Wed Sep 18 14:03"..., 2527) = 2527
    close(5)                                = 0
    munmap(0x4001a000, 4096)                = 0
    rename("CVS/Entries.Backup", "CVS/Entries") = 0
    unlink("CVS/Entries.Log")               = 0
    chdir("/home/ralph/code/groff/x")       = 0
    write(3, "\3\0Q\213#\213", 6)           = 6
    read(4,
