As seen e.g. in the Oscar CI (https://github.com/oscar-system/Oscar.jl/actions/runs/7364368265/job/20044672970#step:7:353) on julia 1.10.

PolymakeExt Waiting for background task / IO / timer.
[pid 3567] waiting for IO to finish:
 Handle type        uv_handle_t->data
 timer              0xa01af90->0x7f67395345b0
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.

Hm, this was fixed with rc2, but now is back, see #1282. Weird

Closing this, since this is a problem in julia.

The upstream bug is JuliaLang/Downloads.jl#223
I have added a workaround in Polymake 0.11.10 that should avoid the message.
