I just found that vibe.d crashes completely when a fiber tries to access
an OOB element of an array. This was a programing error and not a memory
corruption.

Other exceptions will just print an exception to the web page and
continue running. With a web server, it's kind of expected that any
error in a web page will not bring down the whole thing. Is there a way
to specifically catch RangeError and continue to run?
