PHPProcessManager

A PHP Process manager that maintains a pool of reusable PHP instances.

Instances are spawned on demand up to maxPhpInstances and reused across requests. The first instance spawned is the "primary" instance which contains the reference filesystem used by all other instances.

The semaphore controls how many requests can be processed concurrently. When all instances are busy, new requests wait in a queue until an instance becomes available or the timeout is reached.
