Slow pipes after upgrade cygwin 1.5.12-1->1.5.13-1 when running boinc

["Bengt-Arne Fjellner" <Bengt-Arne dot Fjellner at ltu dot se>]

With boinc running einstein@home at lowest priority ( uses 100% cpu but yields easily)
simple pipes takes a long time.
Example: from a bash prompt
echo hello|grep -v xyz
with boinc running and 1.5.13-1 takes about 7 seconds.
if i stop boinc it takes parts of a second.
after downgrade to 1.5.12-1 with boinc running: parts of a second.

i have seen this on two different computers one HT one normal.

Single commands are still fast.
