Steps to reproduce the problem:
Actually I do not know how to reproduce it. Chrome just sporadically spawns new process. 

What is the expected behavior?

What went wrong?
"Utility: Windows Utilities" process consumes CPU at 100%

Did this work before? N/A 

Chrome version: 65.0.3315.0  Channel: n/a
OS Version: 6.3
Flash Version: 

Following is a command line of that process:

"...\chrome-win32\chrome.exe" --type=utility --field-trial-handle=1492,14536991658458675487,15123086131659145668,131072 --lang=en-US --no-sandbox --service-request-channel-token=B495C24BC969E6003FD03362DFD355F2 --mojo-platform-channel-handle=3028 /prefetch:8

This process has just one thread. Following is callstack:
...
KERNELBASE.dll!Sleep+0xf 
chrome_child.dll!GetHandleVerifier+0x1e14b
chrome_child.dll!GetHandleVerifier+0xbb35

In the chrome_child.dll:
10B2FC33  push        0  
10B2FC35  call        dword ptr ds:[12DD743Ch]   // <<< Sleep. So it is Sleep(0)
