    ;; 2008-05-19 change by Larsi:
    ;; Change the default timeout from 0.1 seconds to 0.01 seconds.  This will
    ;; make nntp and pop3 article retrieval faster in some cases, but might
    ;; make CPU usage larger.  If this has any bad side effects, we might
    ;; revert this change.

  ;; When changing this variable, consider changing `pop3-read-timeout' as
