Description of problem:
Liferea is stalling a ton while waiting for fsync() or fdatasync(). 

This shows as main window not rendering, not responding to minimize/close requests, causing "not responding" dialogues and so on.


To verify this is the case, LD_PRELOAD and launch it with fex. :
#include <sys/types.h>

int fsync (int fd)
{
	return 0;
}

int fdatasync (int fd)
{
	return 0;
}

int msync (void *addr, size_t length, int flags)
{
	return 0;
}
