    reduce workspace load on the parameter canary vtc
    
    It now bails out due to a workspace overflow which it acually did
    trigger all the time, but that remained unnoticed due to #3194
    
    The test to multiply the cookie header 128 times (8x in the first
    regex, 16x in the second) was not realistic even for "modern times",
    so I do not think we should have workspaces sized by such an example.
