[BASESRV-CSRSRV]
A little bit of code reorganization (more a "matter of taste"; delete allocated
pointers in the reverse way we allocated them).
[NTDLL]
- Free a used SID (i.e. fix a memory leak).
- Only just "reserve" memory pages for the section for the CSR port. Memory will
be actually committed later on (checked on Windows Server 2003 and on
http://j00ru.vexillium.org/?p=527 ).
