2298 * The client and the server each employ a "BIO pair":

2300 * BIO pairs are symmetric. A BIO pair behaves similar
2301 * to a non-blocking socketpair (but both endpoints must

2303 * [Here we could connect client and server to the ends
2304 * of a single BIO pair, but then this code would be less
2305 * suitable as an example for BIO pairs in general.]

2311 * other side's read attempt

2314 * ..._read_request is never more than ..._write_guarantee;
2315 * it depends on the application which one you should use.
2319 * We have non-blocking behaviour throughout this test program, but
2320 * can be sure that there is *some* progress in each iteration; so we
2321 * don't have to worry about ..._SHOULD_READ or ..._SHOULD_WRITE --
