process module cannot handle big results on Windows

[David Graf]

On Windows, the function exec from the process module cannot handle big results. If the result returned in the tag 'stdout' exceeds a certain size, the process execution gets blocked. The problem can be reproduced with the query attached to the bug.
We guess, the problem can be fixed by using threads to execute subprocesses on Windows. Example Code how to do that can be found at http://support.microsoft.com/kb/190351. Currently, the subprocess pipes the resulting stream into a Windows-pipe, but the parent process doesn't consume it till the end of the subprocess. Therefore, the subprocess blocks as soon as the pipe is full.

changed priority to 4 as this bug doesn't block anybody and it still works for 90% of all use cases.
