The Web streams spec requires promise creation at numerous points, often in hot paths and often invisible to users. Each read() call doesn't just return a promise; internally, the implementation creates additional promises for queue management, pull() coordination, and backpressure signaling.
Code runs in a completely separate, hardware-backed environment with its own guest kernel. It is important to separate the concepts here. The hypervisor is the capability built into the Linux kernel that manages the CPU’s hardware virtualization extensions. The Virtual Machine Monitor is a user-space process that configures the VM, allocates memory, and emulates minimal hardware devices. The microVM itself is a VM that has been stripped of legacy PC cruft so it boots in milliseconds and uses minimal memory.
