- User programs should never spawn domains. To execute a function on a domain, use [Multicore] from the threading library. This is because spawning more than [recommended_domain_count] domains (the CPU core count) will significantly degrade GC performance. Using both [Domain.spawn] and [Multicore] can cause [Multicore] to abort.
