Got some hints on the netbsd mailing list:
---
_res is a structure used by resolver(3) to resolve domain name queries. As
it is used as a global variable, access to it cannot be thread-safe (the
old API does not define a lock that permits the access of this struct in a
thread-safe manner).
Fix:
There should be some piece of code in exim 4.70 that uses _res directly.
It should be rewritten with the res_n*() (res_ninit, res_nsend, ...)
functions, which are thread-safe.

It seems exim implemented the use of the resolver library the wrong way.
(I'm the only one who wants to use exim on netbsd in the whole world?)
thx!
