<title>Runtime Objects</title>

|
<para>
|
|
Each runtime represents a single PHP thread, the thread is created (and bootstrapped) upon construction.
|
|
The thread then waits for tasks to be scheduled: Scheduled tasks will be executed FIFO and then the thread will resume waiting until
|
|
more tasks are scheduled, or it's closed, killed, or destroyed by the normal scoping rules of PHP objects.
|
|

<para>
|
|
When a runtime is destroyed by the normal scoping rules of PHP objects, it will first execute all of the tasks that were scheduled,
|
|
and block while doing so.

<title>Runtime Bootstrapping</title>
|
|
<para>
|
|
When a new runtime is created, it does not share code with the thread (or process) that created it. This means it doesn't have the same
|
|
classes and functions loaded, nor the same autoloader set. In some cases, a very lightweight runtime is desirable because the tasks that
|
|
will be scheduled do not need access to the code in the parent thread. In those cases where the tasks do need to access the same code, it
|
|
is enough to set an autoloader as the bootstrap.
|
|
</para>
|
|
<note>
|
|
<para>
|
|
preloading may be used in conjunction with parallel, in this case preloaded code is available without bootstrapping
