- * Trouble is that unlike Unix file descriptors [which are indexes
- * in kernel-side per-process table], corresponding descriptors on
- * platforms which require "UPLINK" interface seem to be indexes
- * in a user-land, non-global table. Well, in fact they are indexes
- * in stdio _iob[], and recall that _iob[] was the very reason why

- * file descriptors can only be provided by application. Therefore
- * "UPLINK" calls are due...
