Builds fail when many logs stream to stdout at once

[Dan Ryan]

I have recently encountered build failures when building packages using lpcraft which write many logs to stdout during a short time interval which trigger the following error:

error: [Errno 11] write could not complete without blocking
2022-08-19 14:07:24.335 :: Exception ignored in: <_io.TextIOWrapper name='<stdout>' mode='w' encoding='utf-8'>
2022-08-19 14:07:24.335 :: BlockingIOError: [Errno 11] write could not complete without blocking
2022-08-19 14:07:24.335 :: ldItalic

Log is here:

Note that this build succeeds if I pipe stdout to devnull

A relevant detail may be that this build invokes npm to build documentation which logs quite heavily to stdout.
