I am using the acmsmall template and my inline formulas are being broken at equal signs and arrows; how can I prevent them from being typeset like that globally (i.e. without having to put tildes everywhere)?

4@diabonas: Good that you found that question. But here it's about avoiding these line breaks globally. The answers to that other question don't address this.– Hendrik VogtMar 25, 2011 at 14:52

Increase the penalty for line breaks at relation symbols and binary operators:
\relpenalty=9999
\binoppenalty=9999
If you simply include these commands in your preamble (between \documentclass{...} and \begin{document}), it will prevent line breaks in most cases, but in extreme situations, they can still be broken. If you set
\relpenalty=10000
\binoppenalty=10000
equations will never be broken - this may, however, destroy your layout!

\mbox{$equation$} is not an answer, unfortunately: the spacing in the equation doesn't grow or shrink together with the other spaces in the line. The "correct" answer is
$LHS=\nobreak RHS$
TeX will choose another break point, if there is one, or warn about an Overfull \hbox
Diabonas's answer shows how to avoid such breaks globally, and correctly warns about the dangers of doing so.
I found the easiest way to simply wrap the equation within curly brackets preceded by a tilde. See the example below.
Instead of
$x = \{x\,|\,x\in\mathbb{R_{\ge0}}\}$
you would write
$~{x = \{x\,|\,x\in\mathbb{R_{\ge0}}\}}$
