The implementation you sent proves that transaction object needs to
know the superset of all data points that may be needed to carry out
the transaction. I'm saying that such knowledge is not necessarily
available in many situations. E.g., as I embark on constructing a
stack crawl, I don't know the entire set of memory reads I'll need. I
need to make a few reads before I know what other memory, if any, I
need to read. And once I do those secondary reads, I may need to do
additional reads.
This is an example of a debugger operation that would require a ton
of async operations that cannot be simplified using a single APCM
transaction. Now, breaking down the operation to multiple ACPM
transactions may solve the problem...
