+  no-pinshared     By default OpenSSL will attempt to stay in memory until the
+                   process exits. This is so that libcrypto and libssl can be
+                   properly cleaned up automatically via an "atexit()" handler.
+                   The handler is registered by libcrypto and cleans up both
+                   libraries. On some platforms the atexit() handler will run on
+                   unload of libcrypto (if it has been dynamically loaded)
+                   rather than at process exit. This option can be used to stop
+                   OpenSSL from attempting to stay in memory until the process
+                   exits. This could lead to crashes if either libcrypto or
+                   libssl have already been unloaded at the point
+                   that the atexit handler is invoked, e.g. on a platform which
+                   calls atexit() on unload of the library, and libssl is
+                   unloaded before libcrypto then a crash is likely to happen.
+                   Applications can suppress running of the atexit() handler at
+                   run time by using the OPENSSL_INIT_NO_ATEXIT option to
+                   OPENSSL_init_crypto(). See the man page for it for further
+                   details.
