How to set a Max number of parallel VM flows

I have a request-response flow that starts with VM. Is there a way to restrict a number of the requests that could be processed in parallel by the flow? I'm on 3.7. Thanks.

Ps. I've tried using maxThreadsActive in VM connector but it still runs in the "source" thread. This is how the VM connector in defined:

<vm:connector name="myvm" validateConnections="true" doc:name="VM">
        <receiver-threading-profile maxThreadsActive="1"/>
        <vm:queue-profile>
          <default-in-memory-queue-store/>
       </vm:queue-profile>
</vm:connector>

and then in the flow:

<vm:inbound-endpoint exchange-pattern="request-response" path="myqueue" connector-ref="myvm" doc:name="getevent">
    <vm:transaction action="NONE"/>
</vm:inbound-endpoint>

This is how it's called from the "source" flow:

<vm:outbound-endpoint exchange-pattern="request-response" path="myqueue" connector-ref="myvm" doc:name="VM">
    <vm:transaction action="NONE"/>
</vm:outbound-endpoint>

You can configure the number of receiver threads for the connector or your inbound-endpoint to one:

<vm:connector name="VM" validateConnections="true">
    <receiver-threading-profile maxThreadsActive="1"/>
</vm:connector>
<flow name="testFlow1">
    <vm:inbound-endpoint path="in" connector-ref="VM"/>
    <echo-component/>
</flow>

You can control this with the threading profiles. For example:

<configuration >
    <default-threading-profile maxBufferSize="100" maxThreadsActive="20" maxThreadsIdle="10" threadTTL="60000" poolExhaustedAction="RUN" />
</configuration>
