Rewrite of signal-handling (ghc patch; see also base and unix patches)
The API is the same (for now). The new implementation has the
capability to define signal handlers that have access to the siginfo
of the signal (#592), but this functionality is not exposed in this
patch.
#2451 is the ticket for the new API.
The main purpose of bringing this in now is to fix race conditions in
the old signal handling code (#2858). Later we can enable the new
API in the HEAD.
Implementation differences:
- More of the signal-handling is moved into Haskell. We store the
table of signal handlers in an MVar, rather than having a table of
StablePtrs in the RTS.
- In the threaded RTS, the siginfo of the signal is passed down the
pipe to the IO manager thread, which manages the business of
starting up new signal handler threads. In the non-threaded RTS,
the siginfo of caught signals is stored in the RTS, and the
scheduler starts new signal handler threads.
