@item Worker(source)
Constructor to create a new thread (worker) with an API close to the
@code{WebWorkers}. @code{source} is a string containing the module
source which is executed in the newly created thread. Threads normally
don't share any data and communicate between each other with
messages. Nested workers are not supported. An example is available in
@file{tests/test_worker.js}.
The worker class has the following static properties:
@table @code
@item parent
In the created worker, @code{Worker.parent} represents the parent
worker and is used to send or receive messages.
@end table
The worker instances have the following properties:
@table @code
@item postMessage(msg)
Send a message to the corresponding worker. @code{msg} is cloned in
the destination worker using an algorithm similar to the @code{HTML}
structured clone algorithm. @code{SharedArrayBuffer} are shared
between workers.
Current limitations: @code{Map} and @code{Set} are not supported
yet.
@item onmessage
Getter and setter. Set a function which is called each time a
message is received. The function is called with a single
argument. It is an object with a @code{data} property containing the
received message. The thread is not terminated if there is at least
