[ros-kernel] Compile ros-on-ros

[Hartmut Birr]

Hi,    

my minimal configuration for compiling ros on ros is 48Mb ram and 32Mb swap
without c++ (explorer) and 64Mb ram and 32Mb swap with c++. The default size
of the page file is 2MB. But I think you use a larger page file. Currently
there exist a problem within the handling of swap pages. If the memory runs
in an low memory situation all swap pages are assigned to real memory pages.
Currently it is not possible to move an swap page from a ram page, which is
frequently used, to a page without a swap page and which is not used. The
second problem is the implementation of our cache manager. If the section
file alignment is lower than a page, Ros needs some pages for caching and
some other pages for the section. The third problem is the relocation of
system dlls (gdi.dll). Each process needs its one copy of a relocated dll.
The pages cannot be shared between the cache and the processes. All this
private pages consumes memory and swap space.
