-- Windows I/O manager
--- TODO: Switch this to use new I/O manager.
+--
+-- This is the I/O manager based on posix FDs for windows.
+-- When using the winio manager these functions may not
+-- be used as they will behave in unexpected ways.
+--
+-- TODO: This manager is currently the default. But we will eventually
+-- switch to use winio instead.
