Running Win 3.0 in enhanced mode, there seems to be some limit to how
much memory a windows app can allocate which is much less than the
amount of free virtual memory. With over 7Mb free, I could only do
a Global32Alloc of about 1.3 Mb. A second copy of the same program could
simultaneously get about the same amount leaving about 5Mb still free.

I've heard that Windows imposes an arbitrary limit of 1/4 of the available
virtual memory per process. This all seems hard to understand since on a
single user system the problem of a user hogging all the resources isn't
really an issue.

Anyone have any comments or experiance with this?
