+    One most POSIX-compliant systems &my-app; can't properly deal with
+    more than FD_SETSIZE file descriptors at the same time and has to reject
+    connections if the limit is reached. This will likely change in a
+    future version, but currently this limit can't be increased without
+    recompiling &my-app; with a different FD_SETSIZE limit.
