Hello!

I want to say thank you so much for the work you have done, I find ExcelDNA exceptionally useful in incorporating work from my larger data analysis in forms easier to digest and play with for my team. 

I had a slightly more general question, probably due to my lack of C# knowledge. For the ExcelAsyncUtil.RunTask<>(), would there be any issue with having all UDFs run through this, on a separate thread? I know there would be some overhead with the thread creation process, but I expect that to be minimal at best in comparison to the locking of I/O or any even moderately CPU-intense tasks?
 
Thank you,
Joe
