The API is certainly no thing of beauty, as I already remarked here: http://thread.gmane.org/gmane.linux.file-systems/70420/focus=1420228
A description of the API can be found here: https://lwn.net/Articles/531939/
The main problem is the ugliness of changing the meaning of pread()'s 'offset' argument to be a multiplexed [signal queue selector + queue position].
I do wonder if we can do better, though I have no particular solution to offer beyond the sledgehammer of adding a new system call.
Cheers,
Michael
