I’ve run it here in two separate sessions of about 10 minutes each.  Memory usage isn’t growing.  Windows 10 preview, 64-bit OS and 64-bit Cygwin.

I don’t think Cygwin could do that even if it wanted to, given that you don’t have any Cygwin services running.  Once the last Cygwin process dies, the OS *will* release the memory it was holding.

cygcheck didn’t seem to find any BLODA on your system, but that seems a more likely explanation than that Cygwin — a purely user-space program — has somehow caused a kernel-level memory leak.

Try testing with all antimalware software disabled, or better, uninstalled.
