Describe the bug

Apologies for the vagueness but I'm not really sure how to pinpoint this issue.
I'm also not 100% this is an issue with overseer as it only happens periodically
but it does seem to happen only after I run an overseer task.

I work in a very large monorepo at work. I have some custom overseer templates
that I run, e.g. the following

    overseer.register_template({
      name = "Mypy",
      builder = function()
        local file = vim.fn.expand("%")
        local cmd = { "mypy", file }
        return {
          cmd = cmd,
          components = {
            "open_output",
            "base",
          },
        }
      end,
      priority = 10,
      condition = {
        filetype = "python",
      },
    })

where base is

      component_aliases = {
        base = {
          {
            "on_output_quickfix",
            open_on_exit = "failure",
          },
          "on_result_diagnostics_trouble",
          "default",
        },
      },

Often when I run this command and others like it, when the command
finishes my neovim process freezes up and I end up having to kill
the process. I can see that nvim is taking up ~99% CPU before I kill it.
Is overseer doing any scanning of files? I have a similar issue with
neotest and I think it's because after running a test it scans through
every file in the repo.

I've added extra logging and can't see anything untowards in the logs:

[DEBUG] Starting task mypy /path/to/file.py
[DEBUG] Task mypy /path/to/file.py exited with code 0
[DEBUG] task(1)[on_complete_dispose] complete, waiting for output view
[DEBUG] VimLeavePre clean up terminal tasks {}

Full config here:

    overseer.setup({
      templates = {},
      task_list = {
        bindings = {
          ["<C-k>"] = false,
          ["<C-j>"] = false,
          ["<up>"] = "ScrollOutputUp",
          ["<down>"] = "ScrollOutputDown",
        },
      },
      component_aliases = {
        base = {
          {
            "on_output_quickfix",
            open_on_exit = "failure",
          },
          "on_result_diagnostics_trouble",
          "default",
        },
      },
      log = {
        {
          type = "echo",
          level = vim.log.levels.WARN,
        },
        {
          type = "file",
          filename = "overseer.log",
          level = vim.log.levels.DEBUG,
        },
      },
    })

What is the severity of this bug?

blocking (cannot use plugin)

Steps To Reproduce

Run a custom template on a very large repo

Expected Behavior

Neovim shouldn't freeze after running the template.
