spl
 /S?P?L/

    [abbrev, from Set Priority Level] The way traditional Unix kernels
    implement mutual exclusion by running code at high interrupt levels. Used
    in jargon to describe the act of tuning in or tuning out ordinary
    communication. Classically, spl levels run from 1 to 7; ?Fred's at spl 6
    today? would mean that he is very hard to interrupt. ?Wait till I finish
    this; I'll spl down then.? See also interrupts locked out.
