cl-bordeaux-threads - 0.9.4-1 main

BORDEAUX-THREADS is a proposed standard for a minimal MP/Threading interface.
.
It essentially provides a compatibility layer for multi-threading across
multiple CL implementations.
.
Some parts of its implementation-specific code can also be implemented in a
Lisp that does not support multiple threads, so that thread-safe code can be
compiled on both multithread and single-thread implementations without need of
conditionals.
