Multiplying the return value by size like this just isn't right. The
callbacks are supposed to return the actual number of bytes read and written,
not some multiple of the number of bytes.
Suppose one day libcurl used a size of 2 for some reason, with nmemb of 5.
The callback would read or write 2*5=10 bytes in that case and it should
return a value of 10. Multiplying by size like is done above would return
a value of 20.
