This is implicated in a regression: #2564.

This PR adds a test case which reliably expresses a null pointer dereference in workerd (although the test itself frustratingly does not fail). The null pointer dereference could plausibly be the root cause of the segfault in #2564. Reverting the CPU profiling fix causes the null pointer dereference to go away.

This is an attempt to reproduce #2564.

The test doesn't fail as I expect, but it's still useful, so if it passes on all CI, I'm going to leave it uncommented.
We need to revert the fix until we've diagnosed #2564.
