Precompile broken on julia-1.9.0-rc2 (also observed on julia-1.9.0)

[Mrbigmatt]

This succeeded a couple hours ago (and when I pin ConcurrentUtilities to v2.3.1), but seems to be broken now:

We are seeing this also, seems like #32 broke HTTP.jl on 1.9.0

seems ok with julia 1.9.4

we observed that with julia 1.9.0

julia> Threads.@spawn Threads.threadpool() 123
ERROR: LoadError: ArgumentError: unsupported threadpool in @spawn: Threads.threadpool()
Stacktrace:
 [1] var"@spawn"(__source__::LineNumberNode, __module__::Module, args::Vararg{Any})
   @ Base.Threads ./threadingconstructs.jl:363
in expression starting at REPL[1]:1

but with julia 1.9.4

julia> Threads.@spawn Threads.threadpool() 123
Task (done) @0x0000000109fc9460

I tried on Julia 1.9.0, 1.9.1 and 1.9.2. It seems to be broken on 1.9.0 and 1.9.1, but works starting on 1.9.2. Given that, I made a quick work-a-round in #34. I guess there might be a better solution, but not sure if it is worth the effort to figure out a better solution for the two failing point releases? see JuliaLang/julia#50182.

[Mrbigmatt]

Closed with #34
