Bug#382005: yelp: keeps calling poll with zero time-out with gnumeric documentation

[wouter]

Package: yelp
Version: 2.14.2-2
Severity: normal


After opening documentation of gnumeric yelp takes a lot of cpu-time doing nothing. A strace showed about 250 calls per second to 'poll' with zero time-out.

After running yelp for some minutes this call could be isolated (filtered with 'grep poll | sort | uniq -c' ):

  32499 poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}, {fd=8, events=POLLIN|POLLPRI}, {fd=12, events=POLLIN|POLLPRI}, {fd=13, events=POLLIN|POLLPRI}, {fd=14, events=POLLIN|POLLPRI}, {fd=16, events=POLLIN|POLLPRI}, {fd=15, events=POLLIN|POLLPRI}, {fd=11, events=POLLIN|POLLPRI}, {fd=18, events=POLLIN}], 10, 0) = 0

Speculation: something sets an eventloop with a zero time-out.

Greetings,

Wouter Oosterveld
