Just as an update, I went and did some conversion and gutted
FlexImage, removing everything but the crop and resize actions, which
are the only ones I was using anyway. Removed RMagick and rewrote
stuff to use mini_magick. Everything seems to be working OK except an
issue with Tempfile on windows. It seems when I run my code on
Windows, the Tempfile is created and deleted before I'm done with it.
I found some code online that lets me persist tempfiles, which is fine
for me in Win32, since I'm only using it for development.
I did a bit of testing, and I was able to get the memory use of a
single mongrel to max out at about 56mb. Depending on what I was doing
with some images, it spiked to 80mb, but dropped back down to 56,
which is acceptable. This was on mongrel 1.0rc1 btw.
