"BORDEAUX-THREADS is a proposed standard for a minimal
90 MP/threading interface. It is similar to the CLIM-SYS threading and
91 lock support, but for the following broad differences:
93 1) Some behaviours are defined in additional detail: attention has
94 been given to special variable interaction, whether and when
95 cleanup forms are run. Some behaviours are defined in less
96 detail: an implementation that does not support multiple
97 threads is not required to use a new list (nil) for a lock, for
100 2) Many functions which would be difficult, dangerous or inefficient
101 to provide on some implementations have been removed. Chiefly
102 these are functions such as thread-wait which expect for
103 efficiency that the thread scheduler is written in Lisp and
104 'hookable', which can't sensibly be done if the scheduler is
105 external to the Lisp image, or the system has more than one CPU.
107 3) Unbalanced ACQUIRE-LOCK and RELEASE-LOCK functions have been
110 4) Posix-style condition variables have been added, as it's not
111 otherwise possible to implement them correctly using the other
112 operations that are specified.
114 Threads may be implemented using whatever applicable techniques are
115 provided by the operating system: user-space scheduling,
116 kernel-based LWPs or anything else that does the job.
118 To avoid conflict with existing MP/threading interfaces in
119 implementations, these symbols live in the BORDEAUX-THREADS-2 package.
120 Implementations and/or users may also make them visible or exported
121 in other more traditionally named packages."))
