steal a bit more of mallocBytesRWX() from GHC.
Maybe this will fix the Windows DEP problem reported by Brian Smith.
No, it didn't fix it. I think that the problem that needed fixed in GHCi was different than the problem with Hugs.
With the GHCi error, the Windows DEP error dialog box would pop up, (I
believe) asking the user to report the problem to Microsoft, and
providing a button that opened up the DEP settings dialog box.
In the Hugs error, the Windows DEP error dialog box
never pops up. Instead, Hugs just reports that it received an
unexpected signal. The signal it receives is SIGSEGV.
