> The allocator is decided once and for all when the functional interface instance is obtained. Any other call to `apply` will use the same segment allocator specified on creation. To solve this, I believe the only way is to use the default method setup I described earlier. But the patch is good enough as is for now.

Yes, the tradeoff is quite apparent, but I suppose reasonable to an extent. Your solution is probably the best road to go down when playing around with it though 👍.
