Note that the implication here is that openssl depends on the kernel
building and many other pieces of the system depend on openssl so it
does bottleneck the build somewhat. 

It also means a kernel rebuild ends up triggering half the userspace to
rebuild which is annoying for users.

How commonly are kernel crypto drivers used?
