This sounds like something was still broken, and just never understood.

Some more questions...

1) cygrunsrv still uses the cygwin1.dll, so when does it get loaded? (Is it 
when the openlog call is made in service_main?)

2) Are there any known dependencies for the cygwin1.dll? Or is there 
anything known that could make it take too long to load?

3) If it is being loaded at the openlog call, could it take too long 
sometimes? cygrunsrv has 1 second to answer with RegisterServiceCtrlHandlerA 
doesn't it?

4) Can I defer the loading of the cygwin1.dll call somehow? Perhaps by doing 
non-cygwin logging to a file at the beginning? If so, what should the open 
and write calls look like, and how do I compile/build it? (In this area I am 
a newbie.)

5) Is there some better way to debug this? Or other possible approaches?

6) I can always use srvany or invoker if I need to, but I see value to the 
CygWin community in finding the root-cause for this problem.

My two machines are pretty vanilla also, except of course the OS.

Thanks,
