Warning during precompilation on Julia 1.10

[MichaelHatherly]

Precompilation still completes, but includes the following warning.

[pid 4450] waiting for IO to finish:
 Handle type        uv_handle_t->data
 timer              0x10fffe940->0x14d9dfd30
 timer              0x10ff55f10->0x14d9ecb80
This means that a package has started a background task or event source that has not finished running. For precompilation to complete successfully, the event source needs to be closed explicitly. See the developer documentation on fixing precompilation hangs for more help.
  1 dependency successfully precompiled in 11 seconds. 44 already precompiled.
  1 dependency had output during precompilation:
┌ QuartoNotebookRunner

Appears to be due to Malt workers taking some time to close. Diagnose whether it's even worth having those parts precompiled. Perhaps just selectively precompile the surrounding code that doesn't directly interact with the Server objects.
