#2180: Any installed signal handler stops deadlock detection, but XCPU never
happens in a deadlock
--------------------------------+-------------------------------------------
Reporter: Baughn | Owner: Baughn
Type: feature request | Status: new
Priority: normal | Component: Runtime System
Version: 6.9 | Severity: minor
Keywords: | Testcase:
Architecture: Unknown | Os: Multiple
--------------------------------+-------------------------------------------
The runtime system's deadlock detection, being a debugging feature,
rightly doesn't break a deadlock if there's any chance a signal will do so
later. However, if the only installed signal is XCPU - cpu time-limit
exceeded - then that will almost never happen in practice; any program
that does want to wait for it will be waiting quite literally years.
As such, it seems best if XCPU is left out of the signal-detection logic.
The attached patch does this.
