http://cygwin.com/ml/cygwin-cvs/2011-q2/msg00196.html
introduced reordering of SH_- related memory blocks and the following change 

|   -	  unsigned size = offsets[i + 1] - offsets[i];
|   +	  unsigned size = offsets[i] - offsets[i + 1];
|    	  offsets[i] += delta;
|    	  if (!VirtualAlloc (off_addr (i), size, MEM_RESERVE, PAGE_NOACCESS))

However, address range is to be allocated using its LOWER boundary
which is now offsets[i + 1].

Even prior the change, I wondered why member[1] is not also updated.
Hence I also suggest that the allocation of [0], [1] and the last item 
should be double checked and perhaps commented in src.
|          for (int i = SH_USER_SHARED + 1; i < SH_TOTAL_SIZE; i++) 
"SH_USER_SHARED"+ 1 turns out to be 2.


|    	    continue;  /* oh well */
 :-)
