OK. I can confirm that this works. Thanks. I assigned this to ghc was because that the same library worked with ghc 7.2.2 or earlier.

Found the interrupt, virtualTimerExpired. And in the aborted poll call, the timeout (var to in millisec) is 4294967295. Hoping someone be familiar with ghc runtime could help here. Hi Cdornan, I think...

Please assume I know nothing at all about LDAP. Can you give me the complete source code for a program that demonstrates the failure, and tell me which packages it depends on? I can probably find out...
