Probably this is not exactly memory, because problems starts at too low level.
It may be some limit of threads as you described. I checked with 32-bit
applications, the problem is really only for 16-bit CGI, 32-bit ones work

Below is memory usage before first request, after the first request,
after the first CGI request and subsequent failed CGI requests.
In this test CGI was performed well only once, but it may
take several calls before error appears.
