Traceback (most recent call last):
  File "/usr/src/servers/asyncioecho.py", line 4, in <module>
    import uvloop

AttributeError: module 'asyncio.base_events' has no attribute '_check_resolved_address'

Reproduce the failing ./run_benchmarks command for the tcpecho-uvloop benchmarks and start with /usr/src/servers/asyncioecho.py, where the traceback occurs while importing uvloop. Compare the installed uvloop and Python asyncio versions around _check_resolved_address; done means the server starts and the benchmarks can connect successfully.
