List of Phobos functions that allocate memory?

[Ola Fosheim Grøstad" <ola.fosheim.grostad+dlang at gmail.com>]

And with profiling you get the call-frequency between functions, 
so a throw could be replaced with:

if (return_address = 0x1234556){...} // 60%
if (return_address = 0x7899324){...} // 30%
slow_unwinding()

That ought to be obvious.
