Q2: If so, how large can this number be under the worst possible conditions? Q3: Is this more memory than is typically found in a typical embedded ssytem, such as the one found in a Microwave oven? Q4: What is the typical target platform for an RT OS, and what is one of the major target platforms for JAVA? Q5: How provable is a system that depends on garbage collection? My opinion is that RT OS's and portable devices need to run in (compared to most VAX programs) tiny memory footprints for them to be useful. The launch costs alone on the extra memory on its way to Mars are very, very large. Feel free to disagree with me (I'm sure you already do... 8-)).
