Not as such. However, a little generalisation of the aufs or diskd
queueing mechanisms will likely do what you need. There are other
constraints you'll need to address though. I suspect you'll want (from
my arch repository robertc@squid-cache.org--squid:
my squid--diskio--3.0 branch (separates out all the storage layout stuff
from actual diskio, which will ease generalisation of the threaded
engine)
my squid--mempools--3.0 branch (removes global variable manipulation
from mempool alloc and frees, which allows separate pool allocs to be
thread safe, but not those from the same pool. You'll want to have a
sync layer over whatever allocator your compressor/decompressor use).
