 In the current version of McLachlan, the parameter apply_dissipation is
 set to "always" by default.  The corresponding "epsdiss" is set to 0 by
 default.  The dissipation calculation in McLachlan is expensive due to the
 way that it iterates over variables.  Use of the Dissipation thorn or
 similar is usually much faster.  I had not realised that apply_dissipation
 was "always" by default.  I think it should be "never".

 OK to change? (with announcement to the mailing list)
