weird application breakage in 2.5.2-pre5

[Bob_Tracy]

The application is elm2.4.ME+.82 with PGP 6.5.8.  Works fine under
kernel version 2.4.17.  Under 2.5.2-pre5, when I try to encrypt+sign
a message to a particular recipient for which I have two matching keys
on my pgp keyring, no matching pgp key is found.  The *only* difference
between "works" and "doesn't" is the kernel version.

Cranked up the debug level on elm in an attempt to see what's happening,
and at level 41, I notice that the parent (elm) isn't reading anything
from the child (pgp -kv recipient_address).  No error indication of any
kind, so fork(), pipe(), execl(), fdopen(), and fgets() all seem to be
happy.

libc version is 2.2.3.

Possible side-effect of bio changes?

very unlikely I would say, maybe it's an odd scheduler interaction?

I'm happy to report that everything seems to be working fine with
2.5.2-pre9.
