initial QNAM::get non-SSL request is slow due to SSL entropy generation on Windows

In addition to the (fixed) slow get calls in general, the first request experiences an even greater delay (several 100 ms) which gets even longer (4 seconds in our case) if the program makes a significant amount of dynamic allocations beforehand, due to the use of Heap32Next in OpenSSL.
This is especially bad because the request isn’t even over HTTPS.
