So, should Python be changed to use fgets(), available on all ANSI C
platforms, rather than the glibc-specific getline()? That would be
more complicated than the brain-dead easy course of using getline(),
which is obviously why I didn't do it; PyFile_GetLine() had annoyingly
When this was discussed in comp.lang.python, someone also mentioned
getc_unlocked(), which saves the overhead of locking the stream every
time, but that didn't seem a fruitful avenue for exploration.
