Big thank you to rfcdejong for taking over 1 hour to look at the code to try to implement rpcthreads function.
Slimcoin wallet is so outdated (Old Peercoin fork) it will take hundreds of file modifications to implement this feature.
thanks, but i'm not happy with it being that old, which isn't a bad thing but just so many changeset's (bugfixes) aren't included in the code which are fixed in the bitcoin code and alot of other coins
look at the litecoin code, it's implemented in there
https://github.com/litecoin-project/litecoin/blob/master-0.8/src/bitcoinrpc.cppeven a simple changeset as "Sleep()" into MilliSleep() isn't done
it's the fact that Peercoin hasn't implemented the functionality, and slimcoin is "forked" from peercoin
look at the peercoin code, no StartRPCThreads method
and search for -rpcthreads (you won't find it)
