Jest can hang indefinitely in node 12

๐ Bug Report
Jest can hang indefinitely in node 12. I have seen this issue in docker and on osx.
To Reproduce
Steps to reproduce the behavior:
Call a library like get-port-sync
during a jest run on node 12. I think deasync could be triggering this but I am not sure.
Expected behavior

Any news on this? We're seeing something similar with node 12.16.1 and deasync
@bluesxman I added a repo that can reproduce this issue on demand but it got tagged as needs repro so I am not sure how the process works. What js library are you using that uses deasync
I can add it to the bug repo.
We get infinitely hanging tests in Shepherd when we try to bump from node 10 to 12. Not sure if that is helpful?
For what it's worth our solution was to stop using deasync since its potentially problematic. I made an async alternative to what we were using deasync for.
I don't think we're using deasync
just get hanging tests anytime we try to update past node 10.
Turns out we were using deasync from jest-transform-svelte. Moving away from it fixed things for us.
Same issue encountered, is there any workaround besides remove deasync
dependency?

Not that I know of.
