   server for. And there are really good stand-alone ones that have been tested
   and proven for many years. There's no need for you to reinvent them!
 
+  5.18 Does libcurl use threads?
+
+  Put simply: no, libcurl will execute in the same thread you call it in. All
+  callbacks will be called in the same thread as the one you call libcurl in.
+
+  If you want to avoid your thread to be blocked by the libcurl call, you make
+  sure you use the non-blocking API which will do transfers asynchronously -
+  but still in the same single thread.
+
+  libcurl will potentially internally use threads for name resolving, if it
+  was built to work like that, but in those cases it'll create the child
+  threads by itself and they will only be used and then killed internally by
+  libcurl and never exposed to the outside.
