normal cc9b57a2b4 zlib (gzfile_write_raw): do not resize string after .write call
Apparently, a component of Rails implements a buffering .write
method which keeps the String buffer around and makes it unsafe
for us to clear it after calling .write.

This caused Rack::Deflater to give empty results when enabled.

Fortunately, per r61631 / a55abcc0ca,
this misguided optimization was only worth a small (0.5MB) savings
and we still benefit from the majority of the memory savings in
that change.

Thanks to zunda for the bug report.
