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