I see that when I remove 'c-before-change-check-unbalanced-strings from
'c-get-state-before-change-functions' the performance degradation
ceases.  I'm not sure what else is affected by that change, so not sure
if that can be counted as a fix as far as 'csharp-mode' is concerned.

Just wanted to let you know.
