Hi Vadim!  Finalizing the default holesize now and rereading your old
messages.  It seems as if you said no less than 1000 pages, and
approx. 1/10 MAXPAGE (here too, as well as growth maximum default) was
optimal.  I've looked at this, and it adds 2.5 Mb (on 6.2) to the
default build.  Is it worth it?  What do people think?  How often do
applications try to dramatically extend the core?

Take care,

Take a look at (room) output for new GCL build.
I see about 400 allocated pages for contiguous blocks.
Why?  Where this pages come from?  This is quite
unexpected.   As far as I understand larger hole size
doesn't increase neither image size nor RSS, it
increases VM only.
