Concurrent "send console input" schedules can break

Bug Report

System Information

• OS: Ubuntu Linux (20.04 LTS)
• AMP: v2.3.2, built 31/01/2022 (Mainline)

I confirm:

• [x] that I have searched for an existing bug report for this issue.
• [x] that I am using the latest available version of AMP.
• [x] that my operating system is up-to-date.

Symptoms

• What are you trying to do? Setting multiple schedules that may trigger in the same minute, each sending their own command to the input of the Minecraft server.
• What are you expecting to happen? Commands get run sequentially, in any order.
• What is actually happening? ('Nothing' is not an acceptable answer!) The commands sometimes work independently and sometimes get concatenated.

Reproduction

• Set up a Minecraft server (tried Fabric and Paper 1.18.1 so far)

• Create 2 schedules, each triggering every minute

  • Set a command for each, for example say test1 and say test2

• Put a bit of load on ther server. It doesn't have to be laggy, just joining the server does the trick it seems.

• Wait. (In testing, i'm getting a wrongly formatted command every 3-4 minutes, YMMV)

Interesting. Looks like a locking issue, should be simple enough to fix.
