The reason for not recommending cassert in production builds is not
cost but stability. Per the fine manual:
Also, having the tests turned on won't necessarily enhance the
stability of your server! The assertion checks are not categorized
for severity, and so what might be a relatively harmless bug will
still lead to server restarts if it triggers an assertion
failure. This option is not recommended for production use, but
you should have it on for development work or when running a beta
version.
