It'll work because it has to be explicitly enabled by the application,
the OpenSSL library will provide the support on sufficiently capable
platforms, but they won't be used unless explicitly requested, and
they're only useful if there's some sort of asynchronous crypto
engine available.  They're light-weight glue to facilitate new
kinds of low-overhead asynchronous operations.  The use of fibres
will be rather rare until such engines become commonplace.
