Title:
eventlet.tpool.execute() causes creation of unnecessary OS native
threads when running unit tests
Status in OpenStack Compute (nova):
Won't Fix
Bug description:
To cooperate with blocking calls, which can't be monkey-patched, eventlet
provides support for wrapping those into native OS threads by the means of
eventlet.tpool module. E.g. nova-compute uses it extensively to make sure calls
to libvirt does not block the whole process.
When used in unit tests, eventlet.tpool creates a pool of 20 native OS
threads per test running process (assuming there was at least one unit test to
actually execute this part of the code in this process).
In unit tests all blocking calls (like calls to libvirt) are monkey-patched
anyway, so there is little sense to wrap those by the means of tpool.execute()
(as we don't want to test eventlet either).
