+Control the number of worker threads that may be used by @value{GDBN}.
+On capable hosts, @value{GDBN} may use multiple threads to speed up
+certain CPU-intensive operations, such as demangling symbol names.
+While the number of threads used by @value{GDBN} may vary, this
+command can be used to set an upper bound on this number.  The default
+is @code{unlimited}, which lets @value{GDBN} choose a reasonable
+number.  Note that this only controls worker threads started by
+@value{GDBN} itself; libraries used by @value{GDBN} may start threads
+of their own.
