Surely you're not asserting that "using common debugging methods [to]
figure out what's wrong" within the complex internals of Cygwin is an
easy task.

In fact, we have a developer here who did that a couple years ago and
sent a whole slew of fixes to the Cygwin maintainers to various race
conditions which manifested themselves on MP machines.  His opinion is
that the Cygwin developers have always been a bit sloppy about
handling the issues that arise on MP machines.  He has also asserted
that debugging Cygwin internals is very hard, certainly not something
that can be done easily "using common debugging methods."

We're a start-up.  We're in the middle of getting a product out the
door.  My management would hardly appreciate it if I took a week off
from the work that I'm supposed to be doing to learn how the Cygwin
internals work to debug a complicated MP race condition which
intermittently causes our builds to crash.

Mind you, I'm not saying that we don't contribute to open source.  In
fact, our company's culture is very open-source oriented, and we find,
fix and contribute fixes to problems in various open-source packages
all the time.  I'm saying that this particular debugging task is one
that is too time-consuming for anyone in my company to take on right
now.

Short of becoming a Cygwin expert, is there anything I can do to make
it possible for the people who are already Cygwin experts to debug
this problem?
