Correct.

Normally in the threads list I see

TID   Start Address
2192  gpg-agent.exe+0x14e0
5224  ntdll.dll!TpCallbackIndependent+0x238
4696  ntdll.dll!EtwDeliverDataBlock+0x453

With a broken agent two libnpth-0.dll threads remain active infinitely

TID   Start Address
4816  gpg-agent.exe+0x14e0
5884  ntdll.dll!TpCallbackIndependent+0x238
5256  ntdll.dll!EtwDeliverDataBlock+0x453
2716  libnpth-0.dll!npth_setname_np+0x59
5776  libnpth-0.dll!npth_setname_np+0x59

The main thread of the process.
