Comment:

 I've attached a patch to RunTestUtils.pl which implements this feature.
 Both absolute and relative tolerances can be specified with the keywords
 ''VarExpABSTOL'' or ''VarExpRELTOL'' followed by a regular expression to
 match (without the leading m/ or trailing /) and the new tolerance value.
 The specified tolerances override more general tolerances for data files
 whose name matches these regular expressions.  Any set of characters can
 be used for matching as long as there are no whitespaces in the regular
 expression.

 For example:
 {{{
 #!div style="font-size: 80%"
   {{{#!python
   VarExpABSTOL ^Psi4.[xy] 1e-8
   VarExpRELTOL gxx 1e-12
   }}}
 }}}

 More specific tolerances can be specified for all the tests of a thorn or
 just within a test's block.

 The attached patch passed the tests I gave it.  Please review.
