Hi Magnus,
I applied your patch but I don't notice for any improvement in performance with
my test case (I still get only 7 lines/sec).
I tried it with several cygwin 1.7.7-1 revisions
Which version of cygwin sources do you use ?
Did you try it with the latest snapshot ?
Thanks,
Sagi.

I did some testing on my 64-bit Vista system, and it appears that
CreateThread is the main cause.
To test this, I removed the call to sigproc_init in dll_crt0_0 and made sure
it was always called in dll_crt0_1 instead. Suddenly the sigp thread started
executing immediately, and its initialization was complete long before
wait_for_sigthread was called.
Since you obviously have a patch, would you mind sharing it, rather than
just your conclusions from said patch?
Not quite ready for commit as is, but here it is:
