 The RTS uses the pthread-based `Itimer` implementation due to the
 bizarrely crippled timer mechanisms provided imposed by that platform.
 This broke in 999c464da36e925bd4ffea34c94d3a7b3ab0135c which fixed the
 pthreads implementation to correctly pause when unneeded. In doing this,
 however, it introduced a dependency on the RTS's synchronization
 primitives provided by `OSThreads.c` (e.g. `Condition`, `Mutex`).
