Subject: Release the GIL in two more methods:
X-Git-Tag: v2.3c1~603
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=b804390ae386a5c8dbd3c107f0f22ab589d3563b;p=python

Release the GIL in two more methods:
  * sync(), because it waits for hardware buffers to flush, which
    can take several seconds depending on cirumstances (according
    to the OSS docs)
  * close(), because it does an implicit sync()
