Dave,

Your suggestions were good.  I inspected the "bash --login -i -x" 
command from cmd.exe and found nothing in particular hanging although 
the hostname and "id -un" and "id -ng" took a little longer than the 
rest.  Even silly simple things like a 'test' and short sed command all 
take an unusually long time.

I ran the cygcheck command similar to what you suggested:

	cygcheck -s -v -r > /tmp/cygcheck.out  2>&1

and have attached.  Also, as an example of generally slow access to the 
underlying XpSp2 os, an strace output of 'ls' is also attached.  ls was 
never lighning fast in cygwin, but now it takes 2 seconds in a directory 
with 6 files in it.  I can consistently get strace to show a burp that 
looks like this:
	exception C0000005 at 18B5B7C3
right after a pair of:
	_pinfo::set_ctty:
commands.

Complete details are in the attached strace output from command:

	strace -o /tmp/strace_output_for_ls.txt ls

Any tips?  Are you (or anyone else) able to discern any unusual 
incompatible dll's in the cygcheck.out or have any other hunches?

TIA again,
Marc
