Hi -
I'm just beginning to look deeper into this portion of the runtime
code, as I'm planning to pull in the core parts of stpd into the
translator/driver.
I wonder: is there some reason (ideally: data) to believe that the
intricate multi-threaded relayfs copying and subsequent cpu_merging is
necessary? For instance, how bad would a simpler, single-threaded
multi-fd poll() work in the relayfs reading loop? Is merging
on-the-fly impractical? On the transmission kernel-probe side, would
a relay_flush() after every probe handler be impractical?
