Summary:                    minivm: when sending mail and using volgain
Description: 
There's some questionable code in apps/app_minivm.c:sendmail() at around
line 1270 looks odd:

1. tmpfd is opened, but never closed.
2. finalfilename is points to part of the stack that gets de-allocated
soon.

Not sure if it causes a crash, as I ran into a different crash issue on
the same area. A demo patch is attached anyway.
