-Subject: fix: increase concurrency in V8Platform::PostJob()
-
-Refs https://chromium-review.googlesource.com/c/v8/v8/+/4347597/11
-
-PostJob posts |job_task| to run in parallel, and so must call NotifyConcurrencyIncrease()
-on the JobTask. In Node.js, the implementations of CreateJob and PostJob were identical,
-meaning that PostJob calls could potentially never run all their tasks.
-
-This was brought to our attention by the above linked V8 CL, which switched a call from
-CreateJob to PostJob and caused a series of failures.
-
-This should be upstreamed.

 Subject: fix: override createjob in node_platform
 
-This CL changed Platform::CreateJob to an abstract method:
-https://chromium-review.googlesource.com/c/v8/v8/+/3779694
-This patch adds an override for NodePlatform::CreateJob, using
-the same parameters as PostJob.
+Refs https://github.com/nodejs/node/pull/44741/commits/507dd20ef957acf261ec521fcbd81d745b17983c
+
+V8Platform::CreateJob was changed to an abstract method in https://chromium-review.googlesource.com/c/v8/v8/+/3779694,
+and is called by V8Platform::PostJob, so we should only call
+CreateJob in order to most closely match V8Platform default behavior.
+
+This patch can be removed when Electron updates to Node.js v20.
