Comment (by facundo.dominguez):

 I'm attaching the eventlog produced with {{{-Ds}}}. It can be uncompressed
 with:
 {{{
 cat test.eventlog.xz.00 test.eventlog.xz.01 | unxz > test.eventlog
 }}}
 Had to split it to comply with the upload limits of trac.

 It contains an entry produced with
 {{{
 traceEventIO "threadWaitRead: failed with BlockedIndefinitelyOnMVar"
 }}}
 At the point where {{{threadedWaitRead}}} fails.

 I couldn't reproduce the bug with GHC HEAD.

 I'm using the threaded runtime.
