Small memory leak #17
Description
First of all: thank you so much for this great piece of software!
I found a small memory leak in the stl version of your library, it is in line 233:
this->threads[i].reset(new std::thread(f));
As you can see, a new thread is created with new but it is never deleted. Valgrind gives me the following message:
==5111== 1,216 bytes in 4 blocks are possibly lost in loss record 1,514 of 1,551
==5111== at 0x4C31B25: calloc (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so)

I don't think that this error is very important and should be fixed ASAP, but I just wanted to let you know :-)
