Ok, I tripped the error again.  Here it is, in all of its pristine glory:

c:\cygwin\bin\vim.exe (2568): *** MapViewOfFileEx failed, Win32 error 6

Weirdly enough, I did not find this exact message anywhere in the sources
(there's only one occurrence of "MapViewOfFileEx failed" in the current
CVS, and it has other things in the message).  If anyone has any ideas
on where it's coming from, I'd appreciate a pointer.
HTH,
	Igor
