IMO, it does matter.  We have the same problem of non-interuptible IO
on sockets.  It's solved in net.cc by using the `CancelIO' call which
doesn't exist in 95.

My humbly opinion:  95 is really, really old now.  It has been
substituted by two following OSes in the meantime and the third
is coming soon.  Even Microsoft has canceled support for 95 and
I can understand them.  If 95 doesn't work in a specific part of
Cygwin which works fine in 98/ME/NT/W2K/XP, we shouldn't care
anymore.  We just stop to create workarounds which are really only
for 95.
