Busy Wait

Noun · Slang & Abbreviations

Definitions

  1. A wait implemented by repeatedly checking a condition instead of sleeping or yielding efficiently, often used casually to describe wasteful polling. In engineering slang, calling something a busy wait usually means it is chewing resources while pretending to be simple.

    In plain English: A wasteful wait loop that keeps checking instead of pausing efficiently.

    Example: "The CPU spike came from a hidden busy wait in the retry loop, which kept spinning thousands of times a second while the dependency stayed unavailable."
