* As for unconditional usage of "UPLINK" interface in this module.
* 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
* "UPLINK" interface was introduced in first place. But one way on
* another. Neither libcrypto or libssl use this BIO meaning that
* file descriptors can only be provided by application. Therefore
* "UPLINK" calls are due...
