# ### Note: Calling this function twice during one completion operation, such

|

# ### as each other, and the two calls specify the same $_type, currently leads
|
|
# ### to garbled output; see workers/35229 (May 2015) and its thread (which also
|
|
# ### discusses at least two other issues, that may or may not be related to
