Ruby - Concurrent Programming

What will be the output of this Ruby code considering the GIL?

count = 0
threads = 5.times.map do
  Thread.new do
    1000.times { count += 1 }
  end
end
threads.each(&:join)
puts count

A5000

B1000

CMay be less than 5000 due to race conditions

D0

Step-by-Step Solution

Solution:

Step 1: Understand thread increments with GIL
GIL allows one thread at a time, but count += 1 is not atomic and can cause race conditions.
Final Answer:
May be less than 5000 due to race conditions -> Option C
Quick Check:
Non-atomic increments + threads = race condition [OK]

Quick Trick: GIL doesn't prevent race conditions on shared data [OK]
