Repro app -- ClipboardSetLoop.cs

Compile *without* /t:winexe so that it stays attached to the console.  Run it. 
One time in ten at least it will crash with:
[[
D:\>mono ClipboardSetLoop.exe
Stacktrace:

]]


Or, if run in a debugger or with Windows' (full) pageheap diagnostics enabled
on mono.exe it will fail everytime. For the latter like:
[[
D:\>mono ClipboardSetLoop.exe

Unhandled Exception: System.Runtime.InteropServices.ExternalException:
