/* The disable_dep function disables DEP for all Cygwin processes if
the process runs on a Windows Server 2008 with Terminal Services
installed. This combination (TS+DEP) breaks *some* Cygwin
applications. The Terminal Service specific DLL tsappcmp.dll
changes the page protection of some pages in the application's text
segment from PAGE_EXECUTE_WRITECOPY to PAGE_WRITECOPY for no
apparent reason. This occurs before any Cygwin or applicaton code
had a chance to run. MS has no explanation for this so far, but is
rather busy trying to avoid giving support for this problem (as of
2008-11-11).
Unfortunately disabling DEP seems to have a not negligible
performance hit. In the long run, either MS has to fix their
problem, or we have to find a better workaround, if any exists.
Idle idea: Adding EXECUTE protection to all text segment pages? */
