PackageCompiler never ends on julia 1.11.0 with --threads=6

[dpinol]

The following command never finishes on julia 1.11.0 (worked on julia 1.10.5). The precompile_statements_file can be any, even an empty file.

using PackageCompiler
create_sysimage(;sysimage_path="kk.so", precompile_statements_file="../kk.trace", sysimage_build_args=Cmd(["--threads=6"]))

The timer keeps on counting forever (CPU does not show any work done)
[09m:10s] PackageCompiler: compiling incremental system image

The fix is not specifying --threads=6 on sysimage_build_args

Any chance you could do a git bisect on Julia between 1.10 and 1.11, to identify the first broken commit?

This seems to be effectively the same issue as #990, so the git bisect from there should apply here, too. There seem to be two paths leading to the problem.

1. Having JULIA_NUM_THREADS set which is then inherited by the process which creates the final system image
2. Setting -t or --threads in sysimage_build_args.
