LGTM Could you explain, for documentation purposes, why this isn't something Lean core could do? |

Sorry, I missed that message. What are you expecting Lean core to do here? Because we are constructing a Perhaps @kmill should have a look at this and suggest if we can avoid this manual construction in the first place (and confirm whether the PR in its current state is still an improvement over the status quo). |

It looks like the withCurrHeartbeats sets initHeartbeats from IO.getNumHeartbeats. What effect does initializing initHeartbeats here have? Can you come up with a test that validates this?

I think you're right, this has no effect.

I see that Lean.Core.wrapAsync exists, and it does a bit more heartbeats arithmetic. Lean.Core.CoreM.toIO looks relevant.

wrapAsync indeed looks like the right tool, as otherwise the hearbeat counts on one thread are meaninglessly transferred to another thread.
In only one case a `Core.Context` is created from within CoreM, and we inherit from the parent Context the `initHeartbeats`. Otherwise, we get the current heartbeats from IO. Co-authored-by: Laurent Sartran <[email protected]>

Have issues been fixed to everyone's satisfaction? |

lintCoreare; should they inherit the outer heartbeat count (as with this patch), or get a new heartbeat budget for each declaration (prior to it)?
