Bug#637654: libglib2.0-dev: glib programs can'T be run with realtime priority (or any non-SCHED_OTHER regime)

[Marc Lehmann]

Package: libglib2.0-dev
Version: 2.28.6-1
Severity: normal


When trying to run glib-based programs that use threads with realtime priority, they
abort sooner or later:

GThread-ERROR **: file /tmp/buildd/glib2.0-2.28.6/./gthread/gthread-posix.c: line 348 (g_thread_create_posix_impl): error 'Invalid argument' during 'pthread_attr_setschedparam (&attr, &sched)'

this is probably caused by glib expecting to be run as SCHED_OTHER all
the time - it would probably be better to not insist on being able to set
specific priorities, or change the scheduling regime to an appropriate one
(but ignoring the users wish would probably be worse).
