[Mono-dev] Threading issues in page_load event (in ASP.NET on mono)

[arunc3]

True. 
When the thread is taking longer to execute than the script timeout value, 
it is automatically aborted. 
But, won't the users see a plain blank page w/o any messages, if the code
times out?
I want to show a decent message, if the thread is taking too long!

Interestingly this code works *perfectly* on a windows box on IIS. But not
on mono. 

:(
