Protecting against fork bombs

[Adam]

In light of the recent problems with cyclic Xft dependencies, it has
become painfully obvious how quickly a fork bomb can bring my computer
to a complete halt. 

Does FreeBSD provide any solutions for protecting against fork bombs?
When I tried installing Mozilla yesterday morning, the explosion of
'make' processes brought my box to it's knees in minutes. 

I'd really like a way of protecting myself from something like this
happening again.
