I've tried the 20041225 snapshot and had a couple problems:

First, running non-cygwin programs has gotten very noisy.  Note the
"Terminated" and "Signal 15":

$ cygcheck -c cygwin
Cygwin Package Information
Package              Version        Status
cygwin               1.5.12-1       OK

$ sh -c 'cygcheck -c cygwin'
Cygwin Package Information
Package              Version        Status
cygwin               1.5.12-1       OK
Signal 15

Second, perl test are hanging at the termination of ext/io/t/io_sock.t

Commenting out the @INC='../lib' line (so it runs even outside the
perl build directory) and running the test with the cygwin
distribution perl will hang at termination; the perl process no longer
appears in ps when it hangs, and the parent process (whether bash, sh,
or perl) is unresponsive to signals (except that a kill -9 makes
further kills report that the parent process no longer exists, though
it stays in the ps output).

Running the perl test from cmd.exe also hangs.

I will try to pare down the test file and see how much I can isolate
the problem, but wanted to give you a heads up.  The previous snapshot
I tried was 20041218, and it did not have this problem.
