Also if you don't like the SIS implementation, it's simple to change it.
There are two separate implementations already (immediate and delayed).
And they don't take much code:

dovecot-2.0-sis/src/lib-fs% wc -l fs-sis*[ch]
  431 fs-sis.c
   58 fs-sis-common.c
   14 fs-sis-common.h
  322 fs-sis-queue.c
