#4123: Control.Concurrent.MVar doesn't need to depend on the Prelude
---------------------------------+------------------------------------------
Reporter: tibbe | Owner:
Type: bug | Status: new
Priority: normal | Component: libraries/base
Version: 6.13 | Keywords:
Os: Unknown/Multiple | Testcase:
Architecture: Unknown/Multiple | Failure: Building GHC failed
---------------------------------+------------------------------------------
`Control.Concurrent.MVar` currently depends on the `Prelude`, causing an
import cycle in the new I/O manager. This patch replaces the dependency on
the `Prelude` with modules in the `GHC` hierarchy, breaking the cycle.
