More windows

[Simon Peyton Jones]

Oddly it's started working.   I have no idea why.  I'll yell if it breaks again.

| Hi Simon,
| 
| Perhaps let's try this,
| 
|  1. download and run the procmon tool from [1]
|  2. from the "Filter" menu select the "Filter..." option
|  3. select "Path" in the first drop-down
|  4. select "contains" in the second drop-down
|  5. enter "ghc-cabal.exe" in the third text box
|  6. select "Include in the fourth drop-down
|  8. click the "Add" button
|  7. click the "Ok" button
| 
| Now you should be logging events pertaining to the file in question. Now
| simply run `./validate` to try to reproduce the issue.
| 
| With luck this will produce a handful of events, some of which ought to
| point to the process that it responsible for meddling with the GHC
| build.
| 
| Now export this log,
| 
|  1. select "Save" from the "File" menu
|  2. select the "Events displayed using current filter" option
|  3. select the "CSV" format, select a path that will be easy to file
|  4. return this file to me (perhaps via GitHub Gist [2]?)
| 
| Hopefully this will give us some insight into what is happening.
| 
| Cheers,
| 
| - Ben
