6dd3616298 fix: import pending objects *before* moving segments 
@Kha I stopped getting the assertion violation after this fix.
There is another unrelated issue that I will fix in a separate commit.

110ae4b571 feat: replace OS-specific stream redirection with pure-Lean Stream redirection 
This avoids the temporary files workaround on macOS and Windows, and makes sure
we can process a `#eval` command and write messages to stdout at the same time.

c0dbf60830 feat: remove IO.ref.reset 
`reset` was used to implement a "buggy" `IO.ref.modify`.
```lean
@[inline] def Ref.modify {α : Type} (r : Ref α) (f : α → α) : m Unit := do
v ← r.get;
r.reset;
r.set (f v)
```
`IO.Ref.reset` will store a nullptr in `r`.
Now, suppose another thread tries to read this reference,
it will get an `IO.error`.
It is not a crash, but it is really weird behavior.

The following code doesn't terminate (in a reasonable amount of time)
```
def large_nat : Nat := (9223372036854775807 : Nat)
