Describe the bug

SLOAD/SSTOREs are hot after their first load in the test. I would think that hitting a contract would be a signal to invalidate the storage cache (make all storage slots cold) since that would indicate a separate transaction. However, what happens is SLOAD/SSTOREs are kept hot over the course of a test, presumably because it is a single function. Is there a way to work around this, or is this a bug?

i have tried moving the block timestamp forward to see if that helps, but it does not seem to

Hope to have the vm cheatcode for warming/cooling for proper simulations.

Right, slots are warm the whole time since each test is a single transaction. There is an issue for a vm.cool cheatcode here #1340

[zerosnacks]

vm.cool has been added here: #5830

We also have the --isolate mode for improved gas accuracy to run a test in an isolated environment
